A technician compares repair costs for two types of microwave ovens (type I and type II). He believes that the repair cost for type I ovens is greater than the repair costfor type Il ovens. A sample of 60 type l ovens has a mean repair cost of $74.06, with a standard deviation of $16.10. A sample of 68 type Il ovens has a mean repaircost of $67.73, with a standard deviation of $14.70. Conduct a hypothesis test of the technician's claim at the 0.1 level of significance.

The degrees of freedom is, df=n1+n2-2=60+68-2=126 The degrees of freedom is 126. The level of significance is 0.1, then the right tailed area is 1-α=0.90. Computation of critical value: The critical value of t-distribution for 0.90 level of significance at 126 degrees of freedom can be obtained using the excel formula “=T.INV(0.90,126)”. The critical value is 1.29.Decision rule: Reject H0 if test statistic tcalculated greater than (>) critical value 1.29. Thus, the decision rule is Reject H0 if t0 > 1.29.

Types of Error: E In a certain population, the mean mu is 45. There are one thousand statisticians, and none of them know what mu is. Each statistician takes a simple random sample from this population, and each one uses his/her sample to perform the following two-sided test: H0: mu = 42 Ha: mu != 42 The plan is to reject the Null Hypothesis if the P-value is less than 0.05. How many of the statisticians will commit a Type-I error? Group of answer choices ( ) About half of them ( ) None of them. ( ) All of them. ( ) About 50 of them ( ) About 100 of them.

t a nearby college, there is a school-sponsored website that matches people looking for roommates. According to the school's reports, 44% of students will find a match their first time using the site. A writer for the school newspaper tests this claim by choosing a random sample of 165 students who visited the site looking for a roommate. Of the students surveyed, 60 said they found a match their first time using the site. Complete the parts below to perform a hypothesis test to see if there is enough evidence, at the 0.10 level of significance, to reject the claim that the proportion, p , of all students who will find a match their first time using the site is 44% . erform a Z-test and find the p-value. Here is some information to help you with your Z-test. The value of the test statistic is given by −ppp−1pn . The p-value is two times the area under the curve to the left of the value of the test statistic. Standard Normal Distribution Step 1:…

According to a report done last year by the dental industry, 81% of dentists would recommend Starry Whites toothpaste. After some recent negative publicity, the sales team at Starry Whites suspects the proportion of dentists who now recommend the brand is lower. The team chooses 150 dentists at random and asks them whether they'd recommend the brand. Of those, 118 say they'd recommend it. Complete the parts below to perform a hypothesis test to see if there is enough evidence, at the 0.10 level of significance, to conclude that the proportion, p, of all dentists who now recommend this brand is less than 81%. (a) State the null hypothesis Ho and the alternative hypothesis H, that you would use for the test. ( Ho: Aa O 10 under the assumption that the null hypothesis is true.) Here n is the sample size and p is the population proportion you are testing.
Test the hypothesis using the P-value approach. Be sure to verify the requirements of the test. Ho: p= 0.74 versus H,: p#0.74 n= 500, x= 360, a = 0.05 Is npo (1- Po) 2 10? Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or a decimal. Do not round.) O A. Yes, because npo (1- Po) O B. No, because npo (1- Po) =|
