The annual salary for one particular occupation is normally distributed, with a mean of about $132,000 and a standard deviation of about $16,000. Random samples of 26 are drawn from this population, and the mean of each sample is determined. Find the mean and standard deviation of the sampling distribution of these sample means. Then, sketch a graph of the sampling distribution.
Examine the data and identify anything appearing to be unique. Select all that apply. A. The data are presented as quantitative but are actually categorical. B. The unusually large value of 80 minutes appears to be an error in recording the data. C. Most of the data values are rounded to the nearest 5 or 10 minutes, and may be estimates of actual commute times. D. Based on the gaps in the distribution, the data appear to be from two different populations.
You decide that you want to make sure your estimate from part a is correct. You go out and gather 10 simple random samples of 25 people in your school and calculate the proportion of students within each sample whose Amazon packages arrive within two business days of ordering. The proportion of customers that receive their packages within two days of ordering are given below. 0.70, 0.75, 0.6, 0.95, 0.90, 0.73, 0.87, 0.86, 0.92, 0.97 Explain why all of the sample proportions are not the same.
