Computer length is approximately normally distributed with a standard deviation of 8 cm. The factory would like to test the null hypothesis H0: μ=43 cm versus H1: μ>43 cm, using the results of n =25 samples. If the true mean is 45 cm, β = P(type II error) is closest to:

Assume that the blood pressure in Qatari population are normally distributed with standard deviation 25 mmHg. The doctor would like to test the null hypothesis H0: μ = 110 mmHg versus H1: μ ≠ 110 mmHg for a sample of n=16 persons. The acceptance region is 100≤ x̄ ≤ 122. α = P(type I error) is closest to:

Assume the life of a tyre in km’s is normally distributed with mean µ and standard deviation of 5000. To test the hypothesis H0 : µ = 30000 against H1 : µ = 35000 n independent values of lives of tyres are observed and H0 is rejected if the average of these exceed c. Determine n and c if the probability of committing a type I error is 0.01 and the probability of committing a type II error is 0.02

The length of a scarlet macaw is normally distributed with a standard deviation of 5.11 cm. An ornithologist is interested in the mean length of scarlet macaws. He randomly selects 77 scarlet macaws to study, and finds their average length to be 89.5 cm. a) Define the parameter of interest. b) Define the random variable of interest. c) Name the distribution used to construct confidence intervals. (Check the relevant criteria.) d) Construct a 90% confidence interval for the true mean...

The standard deviation for a certain professor's commute time is believed to be 45 seconds. The professor takes a random sample of 25 days. These days have an average commute time of 13.4 minutes and a standard deviation of 53 seconds. Assume the commute times are normally distributed. At the .1 significance level, conduct a full and appropriate hypothesis test for the professor. a) What are the appropriate null and alternative hypotheses?

A sample of size 194, taken from a normally distributed population whose standard deviation is known to be 9.50, has a sample mean of 91.34. Suppose that we have adopted the null hypothesis that the actual population mean is greater than or equal to 93, that is, H0 is that μ ≥ 93 and we want to test the alternative hypothesis, H1, that μ < 93, with level of significance α = 0.05. a) What type of test would be...
