A professor would like to test the hypothesis that the average number of minutes that a student needs to complete a statistics exam is equal to 45 minutes. The correct hypothesis statement would be
A) H0: µ = 45; H1: µ J 45.
B) H0: µ = 45; H1: µ < 45.
C) H0: µ J 45; H1: µ = 45.
D) H0: µ = 45; H1: µ > 45.
Below are the null and alternative Hypothesis,
Null Hypothesis, H0: μ = 45
Alternative Hypothesis, Ha: μ ≠ 45
Option A

A professor would like to test the hypothesis that the average number of minutes that a student needs to complete a statistics exam has a standard deviation that is less than 5.0 minutes. A random sample of 15 students was selected and the sample standard deviation for the time needed to complete the exam was found to be 4.0 minutes. Using α = 0.05, the critical value for this hypothesis test would be ________. a. 6.571 b. 7.261 c. 23.685...
Question 13 (5 points) A professor would like to assess the hypothesis that the average number of minutes that a student needs to complete a statistics trial is equal to 45 minutes.

TV would like to test the hypothesis that the average length of an online video watched by a user is more than 8 minutes. A random sample of 37 people watched online videos that averaged 8.7 minutes in length. It is believed that the population standard deviation for the length of online videos is 2.5 minutes. TV would like to set α = 0.02. The correct hypothesis statement for this hypothesis test would be _________________________. H0: = 8.0; H1: > 8.0...
Expedia would like to test the hypothesis that the average roundtrip airfare between Philadelphia and Paris is higher for a flight originating in Philadelphia when compared to a flight originating in Paris. The following data summarizes the sample statistics for roundtrip flights originating in both cities. Assume that the population variances are equal. Originating City Philadelphia Paris Sample mean $1,240 $1,060 Sample size 15 19 Sample standard deviation $270 $240 A) If Population 1 is defined as flights originating in...
Sony would like to test the hypothesis that the average age of a PlayStation user is different from the average age of an Xbox user. A random sample of 36 PlayStation users had an average age of 34.2 years while a random sample of 30 Xbox users had an average age of 32.7 years. Assume that the population standard deviation for the age of PlayStation and Xbox users is 3.9 and 4.0 years, respectively. Sony would like to set α...

Question 17 (5 points) Entertainment Software Association would like to assess if the average age of "gamers" (those that routinely play video games) is more than 30 years old. A Type II error would occur if Entertainment Software Association concludes that the average age of gamers is Question 17 options: a) 30 years or less when, in reality, the average age is more than 30 years. b) greater than 30 years when, in reality, the average age is 30 years...

Problem 1: Medicare would like to test the hypothesis that the average monthly rate for one-bedroom assisted-living facility is equal to $3,300. A random sample of 12 assisted-living facilities had an average rate of $3,690 per month. The standard deviation for this sample was $530. Medicare would like to set α = 0.05. The correct hypothesis statement for this hypothesis test would be H0: μ ≥ $3,300; H1: μ < $3,300. H0: μ = $3,300; H1: μ ≠ $3,300. H0:...
