Show all work,Lilly collects data on a sample of 40 high school students to evaluate whether the proportion of female high school students who take advanced math courses in high school varies depending upon whether they have been raised primarily by their father or by both their mother and their father. Two variables are found below in the data file: math (0 = no advanced math and 1 = some advanced math) and Parent (1= primarily father and 2 = father and mother). ,,Parent Math,1.0 0.0,1.0 0.0,1.0 0.0,1.0 0.0,1.0 0.0,1.0 0.0,1.0 0.0,1.0 0.0,1.0 0.0,1.0 0.0,1.0 0.0,1.0 0.0,1.0 0.0,1.0 0.0,1.0 0.0,1.0 0.0,1.0 0.0,1.0 0.0,1.0 0.0,1.0 0.0,2.0 0.0,2.0 1.0,2.0 1.0,2.0 1.0,2.0 1.0,2.0 1.0,2.0 1.0,2.0 1.0,2.0 1.0,2.0 1.0,2.0 0.0,2.0 0.0,2.0 0.0,2.0 0.0,2.0 0.0,2.0 0.0,2.0 0.0,2.0 0.0,2.0 0.0,2.0 0.0,,a) Conduct a crosstabs analysis to examine the proportion of female high school students who take advanced math courses is different for different levels of the parent variable.,b) What percent female students took advanced math class,c) What percent of female students did not take advanced math class when females were raised by just their father?,d) What are the Chi-square results?

Can you please show me how you come to the solutions? ,,Q-3a. A stationery store wants to estimate the mean retail value of greeting cards purchased by its customers when they visit the store. A random sample of 15 customers indicates a mean amount of $2.58 with a standard deviation of $0.49 per customer per visit. Assuming a normal distribution, construct a 95% confidence interval estimate of the mean retail value of greeting cards purchased by its customers. ,,Q-3b. A paper manufacturer has a production process that operates continuously throughout an entire production shift. The paper is expected to have a mean length of 11 inches, and the standard deviation of the length is 0.05 inches. At periodic intervals, a sample is selected to determine whether the mean paper length is still equal to 11 inches or whether something has gone wrong in the production process to change the length of the paper produced. You select a random sample of 100 sheets, and the mean paper length is 10.987 inches. Construct a 95% confidence interval estimate for the population mean paper length. ,,Q-3c. A survey of 756 workers asked how much they used the Internet at work. 567 said they used it within limits, and 189 said that they did not use the Internet at work. Construct a 95% confidence interval estimate for the proportion of all workers who use the Internet within limits. ,,Q-3d. You are the designer for your company’s web site. You have data to indicate that the mean download time for the homepage is 6.1 seconds and that the standard deviation of download time is 1.8 seconds. If we assume that the download times are normally distributed, what percent of users will wait between 5 and 10 seconds for the homepage to download? ,
