Answer #1

Answer)

13)

We want to test if u1 is different from u2

Null hypothesis means no difference

So, Ho : u1 = u2

Alternate hypothesis is our research hypothesis

Ha : u1 not equal to u2

So answer is 1)

17)

Type 1 error means rejection of true null hypothesis

Type 2 error means failure to reject the false null hypothesis

Null hypothesis u >= 42.2

Alternate hypothesis u < 42.2

Here we have rejected the null hypothesis

When true average is 30.44

That is average is less than 42.2

And we rejected that u >= 42.2

So yes we have made the correct conclusion

So no error occurede

    Question 14 (1 point) In a consumer research study, several Meijer and Walmart stores were surveyed at random and the average basket price was recorded for each. You wish to determine if the average basket price for Meijer is less than the average basket price for Walmart. It was found that the average basket price for 24 randomly chosen Meijer stores (group 1) was $51.574 with a standard deviation of $11.9675. Similarly, a random sample of 15 Walmart stores (group...

    Does the amount of hazardous material absorbed by the bodies of hazardous waste workers depend on gender? The level of lead in the blood was determined for a sample of men and a sample of women who dispose of hazardous waste as a full time job. You want to test the hypotheses that the amount absorbed by men is less than the amount absorbed by women. After performing a hypothesis test for two independent samples, you see a p-value of...

    Does the amount of hazardous material absorbed by the bodies of hazardous waste workers depend on gender? You want to test the hypotheses that the amount absorbed by men (group 1) is less than the amount absorbed by women (group 2). A random sample of 231 male workers and 197 female workers showed an average lead absorption in the blood of 12.2 (SD = 0.774) and 12.21 (SD = 0.577), respectively (measured in micrograms/deciliter).

    Question 12 (1 point) It is reported in USA Today that the average flight cost nationwide is $380.51. You have never paid close to that amount and you want to perform a hypothesis test that the true average is actually different from $380.51. The hypotheses for this situation are as follows: Null Hypothesis: u = 380.51, Alternative Hypothesis: u 380.51. You take a random sample of national flight cost information and perform a one sample mean hypothesis test. You observe...

    Consumers Energy states that the average electric bill across the state is $42.22. You want to test the claim that the average bill amount is actually less than $42.22. The hypotheses for this situation are as follows: Null Hypothesis: μ ≥ 42.22, Alternative Hypothesis: μ < 42.22. If the true statewide average bill is $30.44 and the null hypothesis is rejected, did a type I, type II, or no error occur? Question 15 options: 1) Type I Error has occurred....
