Please help with the last part of this question Conduct the hypothesis test and provide the test statistic and the critical value, and state the conclusion. A person purchased a slot machine and tested it by playing it 1,240 times. There are 10 different categories of outcomes, including no win, win jackpot, win with three bells, and so on. When testing the claim that the observed outcomes agree with the expected frequencies, the author obtained a test statistic of χ2=16.440. Use a 0.10 significance level to test the claim that the actual outcomes agree with the expected frequencies. Does the slot machine appear to be functioning as expected? The test statistic is 16.440 (Type an integer or a decimal. Do not round.) The critical value is 14.684 (Round to three decimal places as needed.) Please help with this part: State the conclusion.

Sixteen women between the ages of 70 and 80 were randomly selected from the general population ofwomen their age to take part in a special program to decrease reaction time (speed). After the course,the women had an average reaction time of 688 milliseconds. Assume that the mean reaction time forthe general population of women of this age group is 750 milliseconds with a standard deviation of 350milliseconds. (a) Compute a 95% confidence interval for μ, the population mean reaction time for women who havetaken part in the program.(b) Perform a hypothesis test to decide whether the course had a significant effect on reaction times.
