12. Fifty specimens of a new computer chip were tested for speed in a certain application, along with fifty specimens of chips with the old design. The average speed, in MHz, for the new chips was 497.8, and the standard deviation was 19.3 MHz. The average speed for the chips having the old design was 483.2 MHz and the standard deviation was 14.1 MHz. Assume the samples are independent. Conduct a hypothesis test at the 5% significance level to determine whether the mean speed of chips having the new chip design exceeds the mean speed of chips having the old chip design as follows: State the appropriate null and alternative hypotheses. Compute the appropriate test statistic. Compute the P – value. d. а. b. с. State your conclusion in context.

1) A study compared the weight loss of people on a low-fat diet versus people on a low-carb diet. In a sample of 100 obese people on a low-fat diet the sample mean weight loss as 7.6 pounds with a standard deviation of 3.2 pounds. In another sample of 120 obese people on a low-carb diet the sample mean weight loss was 6.7 pounds with a standard deviation of 3.9 pounds. a) Test the hypothesis, at the 5% level of significance, that there is a difference in the mean weight loss of using the 2 different diets. b) What is the p-value?
2. A professional racing team is holding tryouts at its test track. The team requires its drivers to have an average lap time of at most 133 seconds at its test track. The team will use a one sample z-test of significance to determine if they should hire a new driver. An amateur driver completes 10 timed laps of the test track with an average lap time of 140 seconds. If the standard deviation of all lap times at this track is 4.5 seconds, what is the value of the test statistic? Round your answer to two decimal places. Answer value Please show work!!!
12) A state fish hatchery raises trout for stocking streams and lakes. The size of the fish at release time can be controlled to a fair degree by varying the rate of feeding. The target is a mean of 10 ounces; if the fish are too small, those who catch the fish aren’t happy. A random sample of 75 fish were weighed at time of release and it was determined that the mean was 9.66 ounces with a standard deviation of 0.86 ounces. Test to determine if the fish being released have a population mean less than 10 ounces at the 0.01 significance level.
The manager of the shipping department of a mail-order operation located in New York advertises that the length of time it takes for customers in California to receive their orders is 8 days. However, the office has been receiving complaints from customers in California stating that orders do not arrive in time advertised. To learn more about this potential problem, the manager chose a random sample of 15 orders. The sample mean of delivery times was 12.25 days. The sample standard deviation was 3.67 days.The average time it takes for all California customers to receive their orders is to be estimated with a 99% confidence interval. a. The ? − or ? −value that should be used to construct this interval is b. The margin of error is equal to
The coach of a very popular men’s basketball team claims that the average distance the fans travel to the campus to watch a game is 35 miles. The team members feel otherwise. A sample of 16 fans who travel to games was randomly selected and yielded a mean of M= 36 miles and s= 5 miles. Test the coach’s claim at the 5% (.05) level of significance. one-tailed or two-tailed test: State the hypotheses: df= tα or t value for the critical region = sM = t (test statistic)= Decision:
Do political science classes require less writing than history classes? The 41 randomly selected political science classes assigned an average of 13.1 pages of essay writing for the course. The standard deviation for these 41 classes was 5.8 pages. The 44 randomly selected history classes assigned an average of 14 pages of essay writing for the course. The standard deviation for these 44 classes was 5.5 pages. What can be concluded at the � = 0.01 level of significance?
7) A tire manufacturer has been producing tires with an average life expectancy of 26,000 miles. Now the company is advertising that their new tires' life expectancy has increased. In order to test the legitimacy of their advertising campaign, an independent testing agency tested a sample of 85 of their tires. The agency found the mean of the 85 tires to be 27,000 miles and the standard deviation to be 3,970 miles. Use a 0.01 level of significance and test to determine whether the company is using legitimate advertising. (Show all seven steps.)
