In this assignment you will practice building and interpreting confidence intervals. Confidence intervals are used to give a range of plausible values for the population mean or proportion under consideration. If you have ever read the results of a poll, you might recall that a percentage is given followed by the statement, "...plus or minus..." some value. For example, the presidential approval rating is 49% plus or minus 1.73%. The 49% is the sample proportion with the 1.73% noting the margin of error. Understanding how confidence intervals are built and interpreted will help you become a better consumer of information. Confidence intervals are used in a variety of applications besides analyzing polling data. For instance, manufacturing clothing (sizes are based on an average plus or minus an acceptable error), volume of food items (the 12 oz cereal box holds on average 12 oz plus or minus a margin of error), lifetimes of items (a lightbulb will last on average 400 hours plus or minus an acceptable error), etc. Task Based on USDA suggestion, a U.S. adult should be spending anywhere from 165 to 345 per month on food, depending on age and gender. A random sample of 120 adults in Washington State is polled regarding the amount of money they spend each month on food. The sample has an average of 273.61 with a standard deviation of 61.59. Based on this information, complete the following questions. a) (5pts)Show that the requirements to build a confidence interval are met. b) (5 pts) State the critical value for a 90% confidence interval c) (5pts)Compute the 90% confidence interval. State values to two decimal places. d) (5pts) Interpret the 90% confidence interval using complete sentences.

Cadmium, a heavy metal, is toxic to animals. Mushrooms, however, are able to absorb and accumulate cadmium at high concentrations. Some governments have a safety limit for cadmium in dry vegetables at 0.48 part per million (ppm). A research team measured the cadmium levels in a random sample of edible mushrooms, where the hypothesis test is to decide whether the mean cadmium level in the sample is less than the governments' safety limit. The null and alternative hypotheses are H0: μ=0.48 ppm, Ha: μ<0.48 ppm. Complete parts (a) through (e) below. A. type II error B. correct decision because a false null hypothesis is rejected C. correct decision because a true null hypothesis is not rejected D. type I error e.

I recently bought the Meta Quest 3, which is a great example of how building trust with a customer can bring in continued sales, as I had already owned the Quest 2. While I could have branched out and tried a new kind of VR headset, I already trusted their previous product, and knew it would be reliable, so decided to go with a known quantity. Another reason I decided to stick with the Meta Quest is because I already owned games for the Quest 2. If I changed VR headsets, I would lose access to the games, wasting the money I already spent. I don't often make big purchases like a brand new VR headset, and though I had been eyeing the Quest 3 for a while, I didn't think I would buy it, but it was their trailer for the new game Asgard's Wrath 2 which came along with the Quest 3, which pushed me over the edge into buying. The graphics looked amazing in them, and I knew that I would never be able to experience that with the old Quest 2. So even though it was only about 60 dollars worth, the added game pushed me into buying.
