Three randomly selected households are surveyed. The numbers of people in the households are 2, 4, and 12. Assume that samples of size n=2 are randomly selected with replacement from the population of 2, 4, and 12. Listed below are the nine different samples. Complete parts (a) through (c). 22,22 22,44 22,1212 44,22 44,44 44,1212 1212,22 1212,44 1212,1212 a. Find the median of each of the nine samples, then summarize the sampling distribution of the medians in the format of...

Question 1. Thirty graduate students were asked how many credit hours they were taking in the current quarter. Download the available data: Calculate the mean, median, standard deviation, variance, and range for this sample using Excel. Write a sentence explaining what each measure means. What is the standard error of the mean based on the data? What would be the best point estimate for the population credit hours? (“Population” refers to all graduate students’ credit hours in the universe.) What...

Three randomly selected households are surveyed. The numbers of people in the households are 1, 4, and 10' Assume that samples of size n 2 are randomly selected with replacement from the population of 1, 4, and 10. Construct a probability distribution table that describes the sampling distribution of the proportion of even numbers when samples o sizes n = 2 are randomly selected Does he mean o the...
ol Commuting to work: A community survey sampled 1923 people in Colorado and asked them how long it took them to commute to work each day. The sample mean one-way commute time was 24.6 minutes with a standard deviation of 13 minutes. A transportation engineer claims that the mean commute time is less than 25 minutes. Do the data provide convincing evidence that the engineer's claim is true? Use the a=0.10 level of significance and the P-value method with the...
