An experiment was performed to compare the abrasive wear of two different coating materials on the cutting tools: • Coating material A: 11 pieces were tested, which gave average wear of 85 units with a sample standard deviation of 4 units. • Coating material B: 10 pieces were tested, which gave average wear of 81 units with a sample standard deviation of 5 units. Assume the populations to be normal. 1) Can we conclude at the 0.05 level of significance that the population variances of material A and material B are different? 2) Can we conclude at the 0.05 level of significance that the abrasive wear of material A exceeds that of material B if the population variances of material A and B are equal?
Data were collected on annual personal time (in hours) taken by a random sample of 16 women (group1) and 7 men (group 2) employed by a medium sized company. The women took an average of 24.75 hours of personal time per year with a standard deviation of 2.84 hours. The men took an average of 21.89 hours of personal time per year with a standard deviation of 3.29 hours. The Human Resources Department believes that women tend to take more personal time than men because they tend to be the primary child care givers in the family. The results of the test are t = 2.00 with an associated P-value of 0.0367. The correct conclusion at a = 0.05 is to A. reject the null hypothesis. B. fail to reject the null hypothesis. C. conclude that women take a higher average number of hours of personal time per year compared to men. D. Both B and C. E. Both A and C. O A O O O B D ΟΕ
3. It was believed that implementing strict measures is key in reducing the spread of a new virus. A random selection of 50 regions with relaxed measures and 55 regions with strict measures were surveyed how many cases they have. It was found that among regions with relaxed measures, the average number of cases per million is 50,000 with standard deviation of 35,000. Among regions with strict measures, the average number of cases per million is 60,000 with standard deviation of 30,000. Using 5% level of significance, conduct a hypothesis test to determine if strict measures is effective in reducing cases in regions with lower standards of living. In words, define the random variable X1 = b. Но с. На: d. The level of significance is e. Determine the test statistic using the data (show solution). f. Provide the decision rule of the test. g.

The breaking strengths of cables produced by a certain manufacturer have a mean, u, of 1875 pounds, and a standard deviation of 100 pounds. It is claimed that an improvement in the manufacturing process has increased the mean breaking strength. To evaluate this claim, 50 newly manufactured cables are randomly chosen and tested, and their mean breaking strength is found to be 1912 pounds. Can we support, at the 0.1 level of significance, the claim that the mean breaking strength has increased? (Assume that the standard deviation has not changed.) Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places, and round your responses as specified below. (If necessary, consult a list of formulas.) (a) State the null hypothesis H and the alternative hypothesis H,. p H, :0 H, :0 (b) Determine the type of test statistic to use. (Choose one) ▼ D=0 OSO O20 (c) Find the value of the test statistic.

A new computer chip design(A) is being compared to the current design(B).Fifty independent chips of each design are tested for speed at performing a certain task. The new computer chip (A) performed the task in 481.2 ms, on average, with a sample standard deviation of 14.3 ms. The current computer chip (B) performed the task in 495.6 ms, on average, with a sample standard deviation of 16.4 ms. Can you conclude, at a 5% significance level, that chip A performs this task faster than chip B?
A turkey geneticist wishes to select for breed-ing purposes hens whose eggs have an average weight of 100 grams. Hens with eggs less than or greater than this mean weight are unaccept-able. The mean weight of a sample of 20 eggs from one hen was 97 grams, with a standard deviation of 2.5 grams. Should this hen be kept in the breeding program?
9) Steel rods are manufactured with a mean length of 25 centimeters (cm). Because of variability in the manufacturing process, the lengths of the rods are approximately normally distributed, with a standard deviation of 0.07 cm. What proportion of rods has a length less than 24.9 cm? b. C. d. 25 Any rods that are shorter than 24.85 cm or longer than 25.15 cm are discarded. What proportion of rods will be discarded? Using the results of part (b), if 5,000 rods are manufactured in a day, how many should the plant manager expect to discard? If an order comes in for 10,000 steel rods, how many rods should the plant manager manufacture if the order states that all rods must be between 24.9 cm and 25.1 cm?

The average undergraduate cost for tuition, fees, and room and board for two-year institutions last year was $14,124. The following year, a random sample of 20 two-year institutions had a mean of $17,124 and a standard deviation of $3700. Is there sufficient evidence at the alpha level of 0.05 to conclude that the mean cost has increased. Show 6 steps of hypothesis
A company has a policy of retiring company cars; this policy looks at number of miles driven, purpose of trips, style of car and other features. The distribution of the number of months in service for the fleet of cars is bell-shaped and has a mean of 55 months and a standard deviation of 8 months. Using the empirical rule (as presented in the book), what is the approximate percentage of cars that remain in service between 31 and 47 months?
