QUESTION 13 A consumer products company is formulating a new shampoo and is interested in foam height (in millimeters). Foam height is approximately normally distributed and has a standard deviation of 20 millimeters. The company wishes to test Ho : μ = 175 millimeters versus H1: μ > 175 millimeters, Using the results of 10 samples. If the critical region is $x$ > 185, What is the the power of the test if the true mean foam height is 185 millimeters? a. 0.9429 b. 0.0571 c. 0.5 Od. 0.05 QUESTION 14 The mean water temperature downstream from a discharge pipe at a power plant cooling tower should be no more than 100°F. Past experience has indicated that the standard deviation of temperature is 2°F. The water temperature is measured on nine randomly chosen days, and the average temperature is found to be 98°F. What are the appropriate null and alternative hypotheses? Οα. Η: μ≤ 100 vs Η: μ> 100 b. Η: μ> 100 vs Η: μ≤ 100 Ο. Η: μ = 100 vs Η: μ≠ 100 Od.

          QUESTION 13
A consumer products company is formulating a new shampoo and is interested
in foam height (in millimeters). Foam height is approximately normally
distributed and has a standard deviation of 20 millimeters. The company wishes
to test Ho : μ = 175 millimeters versus H1: μ > 175 millimeters, Using the results
of 10 samples. If the critical region is $x$ > 185, What is the the power of the test if
the true mean foam height is 185 millimeters?
a. 0.9429
b. 0.0571
c. 0.5
Od. 0.05
QUESTION 14
The mean water temperature downstream from a discharge pipe at a power
plant cooling tower should be no more than 100°F. Past experience has indicated
that the standard deviation of temperature is 2°F. The water temperature is
measured on nine randomly chosen days, and the average temperature is found
to be 98°F. What are the appropriate null and alternative hypotheses?
Οα. Η: μ≤ 100 vs Η: μ> 100
b. Η: μ> 100 vs Η: μ≤ 100
Ο. Η: μ = 100 vs Η: μ≠ 100
Od. Η: μ≥ 100 vs Η: μ<100
QUESTION 15
The mean water temperature downstream from a discharge pipe at a power
plant cooling tower should be no more than 100°F. Past experience has indicated
that the standard deviation of temperature is 2°F. The water temperature is
measured on nine randomly chosen days, and the average temperature is found
to be 98°F. The value of the test statistic is
a.-1
b. 3
c. 1
d.-3
