Compute the sum of ranks for each sample with ties, the mean of the test statistic, the standard deviation of the test statistic and the ?-value. Do not use a continuity correction for the ?-value. Give the sum of ranks to one decimal place, the mean and standard deviation both to two decimals, and the ?-value to four decimals. sum of ranks for female, ?1=

The average cholesterol level in the general US population is 189 mg/dL. A researcher wants to see if the average cholesterol for men in the US is different from 189 mg/dL. She takes a sample of 81 American males and finds a sample mean of 194 mg/dL and a sample standard deviation of 10.4. Create a 90% confidence interval for the true average cholesterol level of the general US male population. What is the 90% confidence interval? What is the...

A simple random sample generated 12 male and 18 female adults identified by their primary care physicians as being over-weight. These adults were fed a special high protein diet for a month and had a sample mean weight loss of 10 pounds with a sample standard deviation of 3.2 pounds. We would like to conduct a test to determine whether the average weight loss for all adults is less than 11 pounds at a 1% level of significance. What would...

Take your survey data and code the gender question as Male= 0 and Female = 1. Suppose we hypothesize that women are more likely to respond to surveys than men are. Specifically, we believe that more than 55 percent of all respondents are women which equates to the proportion of the gender variable to be greater than 0.55. Test the hypothesis. Females= 24 Males= 9 Provide the 6 step process of testing the hypothesis. Present your results and discuss why...
