A computer repair firm believes that its average repair time is less than two weeks. Using the accompanying data that gives the computer repair times in days, determine if the company can continue to support this claim. Use a level of significance of 0.05. Click the icon to view the computer repair times. Is there sufficient evidence at the 0.05 level of significance that the average repair time is less than two weeks? Determine the null hypothesis, $H_0$, and the alternative hypothesis, $H_1$. $H_0$: $mu$ $ge$ 14 days $H_1$: $mu$ $<$ 14 days (Type integers or decimals. Do not round.) Compute the test statistic. (Round to two decimal places as needed.)

A digital camcorder repair service has set a goal not to exceed an average of 5 working days from the time the unit is brought in to the time repairs are completed. A random sample of 12 repair records showed the following repair times (in days): 7, 3, 6, 6, 4, 7, 7, 5, 5, 8, 4, 10. (a) H₀: μ ≤ 5 days versus H₁: μ > 5 days. At α = .05, choose the right option. a. Reject H₀ if t_calc > 1.7960 b. Reject H₀ if t_calc < 1.7960 (b) Calculate the test statistic. (Round your answer to 3 decimal places.) Test statistic (c) The null hypothesis should be rejected. TRUE FALSE

The time to repair an electronic instrument is a normally distributed random variable measured in hours. The repair times for 15 such instruments chosen at random are as follows: Hours 159 280 101 212 224 379 179 264 222 362 168 250 149 260 485 (a) You wish to know if the mean repair time exceeds 225 hours. Set up appropriate hypotheses for investigating this issue. (b) Test the hypotheses you formulated in part a). What are your conclusions? Use a = 0.05. (c) Find the P-value for this test: (d) Construct a 95 percent one-sided lower bound confidence interval for mean repair time. What conclusion can you draw about the hypotheses set up in (a) and why?
