3. Assume that the distribution of the length X of male spider is N(ux,o}) and the length Y of female spiders is N(µy,o?), and X and Y are independent. Construct approximated 95% one-sided confidence intervals for o? /o? when n = m = 30, and = 0.4399 and S? = 1.4100.
#1) Flying time on an old route between 2 cities has a mean value of µ =5.25 hours with standard deviation is o =0.6 hours. There are 36 flights on a new route where the mean is x = 4.90 hours. Does this indicate that the average flying time for the new route is less than 5.25 hours? Use a 5% level of significance.

Q3. A company for fuel stations wanted to check two fuel pumps since there was a doubt that there is a difference in the average pumping time. From previous reconds they knew that Pump 1 has o = 4 mins and Pump 2 has o2 = 3.5 mins. A sample of size 100 from each pump is tested and they found that the average time for each as = 10 mins and i = 8.8 mins respectively. Check with the significance of a = 0.05 whether there is a difference in pumping time or not.

Suppose the mean IQ score of people in a certain country is 103. Suppose the director of a college obtains a simple random sample of 37 students from that country and finds the mean IQ is 107.4 with a standard deviation of 13.8. Complete parts (a) through (d) below. (a) Consider the hypotheses Ho: H= 103 versus H: u> 103. Explain what the director is testing. Perform the test at the a = 0.01 level of significance. Write a conclusion for the test. Explain what the director is testing. Choose the correct answer below. A. The director is testing if the sample provided sufficient evidence that the population mean IQ score is actually greater than 103. B. The director is testing if the sample provided sufficient evidence that the population mean IQ score is actually not equal to 103. O C. The director is testing if the sample provided sufficient evidence that the population mean IQ score is actually equal to 103. O D.

7. For each of the following samples that were given an experimental treatment,test whether they represent populations that score significantly higher thanthe general population: (a) a sample of 100 with a mean of 82, (b) a sample of10 with a mean of 84. The general population of individuals has a mean of 81,a standard deviation of 8, and follows a normal curve. For each sample, carryout a Z test using the five steps of hypothesis testing with a one-tailed test atthe .01 significance level, and make a drawing of the distributions involved.(c) ADVANCED TOPIC: Figure the 99% confidence interval for parts (a)and (b).
