This question: 1 point The accompanying table describes results from groups of 8 births from 8 different sets of parents. The random variable x represents the number of girls Click the icon to view the table. 0.0312 (Type an integer or a decimal. Do not round.) b. Find the probability of getting 1 or fewer girls in 8 births. 0.0352 (Type an integer or a decimal. Do not round.) c. Which probability is relevant for determining whether 1 is a significantly low number of girls in 8 births: the result from part (a) or part (b)? A. Since the probability of getting 0 girls is less likely than getting 1 girl, the result from part (a) is the relevant probability. B. Since the probability of getting more than 1 girl is the complement of the result from part (b), this is the relevant probability. C. Since getting 0 girls is an even lower number of girls than getting 1 girl, the result from part (b) is the relevant probability. D. Since the probability of getting 1 girl is the result from part (a), this is the relevant probability. d. Is 1 a significantly low number of girls in 8 births? Why or why not? Use 0.05 as the threshold for a significant event. A. Yes, since the appropriate probability is less than 0.05, it is a significantly low number. B. No, since the appropriate probability is greater than 0.05, it is not a significantly low number. C. No, since the appropriate probability is less than 0.05, it is not a significantly low number. D. Yes, since the appropriate probability is greater than 0.05, it is a significantly low number.

To demonstrate springs in a two-dimensional lattice, you build the apparatus shown below that is composed of 8 parallel chains of springs, with each chain containing 2 identical low-mass springs in series. At the top and bottom, the springs are attached to a lightweight rod. A mass of 10 kg is attached to the bottom rod. Relaxed, the distance d from the bottom to the top of the apparatus is 0.12 m . (The top of the apparatus is attached to the ceiling in the lab which is not shown.) Each of the 16 springs has a stiffness of 48 N / m. If you support the bottom of the apparatus at rest and if d=0.503 m, what is the magnitude of the force by your hand on the apparatus? Fhand = i N

The passage below discusses some of the steps of an engineering-design challenge. Select the part of the passage that describes constraints. Hint: Constraints are factors that limit the possible solutions. a prototype of a water filter Maura and Tony are working on a project for the upcoming science fair. Their plan is to design a water filter using only a water bottle and natural materials found in or near a local stream. They make a crude filter by combining rocks and sand in the water bottle. Maura and Tony then pour stream water through their filter and analyze this filtered water with a microscope. They find that while the filter removed dirt and pieces of plants, it did not remove all of the bacteria. For their next model, they add a layer of silt to their filter.

Flavia was curious if a sample first quartile (or Q1) was an unbiased estimator of a population first quartile. She started with a large normally distributed population of test scores whose first quartile was Q1=70 points. She then took a random sample of 6 tests and calculated the first quartile of the sample. She replaced those tests and repeated this process for a total of 50 trials. Her results are summarized in the dotplot below, where each dot represents the first quartile from a sample of 6 tests. Based on these results, does sample first quartile appear to be a biased or unbiased estimator of population first quartile? Hint: The population first quartile is 70. Choose 1 answer: (4) Sample first quartile appears to be a biased estimator since it consistently underestimated the population first quartile. (0) Sample first quartile appears to be a biased estimator since it consistently overestimated the population first quartile. (c) Sample first quartile appears to be an unbiased estimator of the population first quartile.

Adames Corporation has two manufacturing departments-Cutting and Forming. The company used the following information at the beginning of the year to calculate predetermined overhead rates: - Estimated total direct labor-hours (DLHs): Cutting 6,000, Forming 23,000 - Estimated total machine-hours (MHs): Cutting 13,500, Forming 2,800 - Estimated total manufacturing overhead cost (fixed and variable): Cutting 732,000, Forming 247,000 During the most recent month, Adames started and completed one job. There were no beginning inventories. Information concerning the completed job is as follows: - Direct materials: Cutting 82,600, Forming 12,300 - Direct labor cost: Cutting 11,600, Forming 31,000 - Actual machine-hours: Cutting 1,700, Forming 140 - Actual direct labor-hours: Cutting 480, Forming 1,500 Assume that the company uses separate departmental predetermined overhead rates with the Cutting Dept using machine-hours as the allocation base and the Forming Dept using direct labor-hours. 1. Calculate the predetermined overhead rates for the Cutting and Forming departments separately (round to the nearest cent). 2. Using the departmental rates, calculate the total manufacturing overhead that would be applied to the job. 3. Calculate the cost per unit for the job if the job included 1,250 units (round to the nearest cent). 4. If the company had instead used one plantwide overhead rate, would you expect the job cost to be more or less accurate than what you calculated above?
