### Chi-Square Test of Independence: Flu Shot and Flu IncidenceYou are conducting a test of independence to examine if getting the flu is independent of whether or not you got a flu shot. Use \(\alpha = 0.05\). Report all answers accurate to four decimal places.Here is the sample data:| Category | Got the Flu | Did not get the Flu ||---------------------|-------------|---------------------|| Got Flu Shot | 18 | 118 || Did not get Flu Shot| 51 | 19 |#### Expected ObservationsThe expected observations for this table would be:| Category | Got the Flu | Did not get the Flu ||---------------------|-------------|---------------------|| Got Flu Shot | | || Did not get Flu Shot| | |#### Chi-Square CalculationThe resulting \(\frac{(O - E)^2}{E}\) for finding the test are:| Category | Got the Flu | Did not get the Flu ||---------------------|-------------|---------------------|| Got Flu Shot | | || Did not get Flu Shot| | |#### Chi-Square Test StatisticWhat is the chi-square test-statistic for this data? (add the results from the previous table)\[\chi^2 = \]#### P-Value CalculationWhat is the p-value for this test-statistic?P-Value = On this educational webpage, detailed explanations and step-by-step calculations will follow this initial setup to guide you through each stage of conducting a chi-square test of independence.

An educational psychologist is studying two methods of tutoring young children: Method A and Method B. She wants to test whether there is any difference in puzzle solving skills between children tutored by one method versus children tutored by the other. Independent samples of 11 children who were tutored using Method A and 10 children who were tutored using Method B were chosen at random. The Method A children took a mean of 43 minutes to solve a certain puzzle with a standard deviation of 8 minutes. The Method B children took a mean of 42 minutes to solve the same puzzle with a standard deviation of 7 minutes. Assume that the two populations of completion times are normally distributed and that the population varlances are equal. Construct a 90% confidence interval for the difference u,-H, between the mean puzzle-solving times for Method A children (u) and for Method B children (1,). Then find the lower limit and upper limit of the 90% confidence interval. Carry your intermediate…
