Solution Steps

Step 1: Find the length of Dayton Ave. along the plot.

The perimeter of the plot is 240 ft. The lengths of the sides are 68 ft, 52 ft, and two unknown equal sides marked with double hash marks. Let 'x' be the length of each unknown side. So, 240 = 68 + 52 + 2x 240 = 120 + 2x 120 = 2x x = 60 ft

The section of Dayton Ave. along the plot has a length equal to one of the sides marked with a single hash mark. This side has a length of 52 ft.

Step 2: Calculate the number of trees.

One tree is planted every 20 ft. The length of Dayton Ave. along the plot is 52 ft. Number of trees = Length of Dayton Ave. / Spacing between trees Number of trees = 52 ft / 20 ft = 2.6

Step 3: Round down to the nearest whole number.

Since we can only plant whole trees, we round 2.6 down to 2.

The length of human pregnancies is approximately normal with mean μ=266 days and standard deviation σ=16 days. Complete parts (a) through (f). B. If 100 independent random samples of size n=14 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of 258 days or more. C. If 100 independent random samples of size n=14 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of 258 days or less. (d) What is the probability that a random sample of 29 pregnancies has a mean gestation period of 258 days or less? The probability that the mean of a random sample of 29 pregnancies is less than 258 days is approximately 0.0035 (Round to four decimal places as needed.) Interpret this probability. Select the correct choice below and fill in the answer box within your choice. (Round to the nearest integer as needed.) A. If 100 independent random samples of size n=29 pregnancies were obtained from this population, we would expect 0 sample(s) to have a sample mean of 258 days or less. B. If 100 independent random samples of size n=29 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of 258 days or more. C. If 100 independent random samples of size n=29 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of exactly 258 days. (e) What might you conclude if a random sample of 29 pregnancies resulted in a mean gestation period of 258 days or less? This result would be so the sample likely came from a population whose mean gestation period is 266 days.
