Suppose we are dealing with the null hypothesis that the average food expenditure of all families in Atlanta is 20 dollars a day. To test the hypothesis we collect a sample of n = 100. We get the sample mean of 22 and the sample variance of 25. Write down the value of t-statistics and corresponding p-value. Will you reject the null? Explain. Only yes or no answer will not be accepted.

In studying the dairy food expenditure of families in a city, random samples of fifty families and forty families are selected from urban area and rural area, respectively. Selected families from urban area have a mean of $150 and a standard deviation of $30. Selected families from rural area have a mean of $135 and a standard deviation of $25. Construct a 95% confidence interval for the difference of mean daily food expenditure between all families of urban area and...

We wish to test the null hypothesis that the employee benefits (in millions) of all companies in a given industry follows a normal distribution with mean 10 and variance 4. In order to do so, we have observed the benefits for 100 companies, from which 30 had benefits smaller than 8, 50 had benefits between 8 and 13, and the remaining 20 firms had benefits larger than 13. The chi-square test statistic is given by a. 2.53 b.7.38 c. 30.60...
