- A maker of frozen meals claims that the average caloric content
of its meals is 400, and the standard deviation is 15. A researcher
tested 16 meals and found that the average number of calories was
350.
At α = 0.10, which of the following is true?
a. The critical values for the test are ± 1.65.
b. The critical values for the test are ± 1.96.
c. Do not reject the null hypothesis.
d. There is enough evidence to support the claim.
Homework Answers
To Test :-
H0 :- µ = 400
H1 :- µ ≠ 400
Reject null hypothesis if | Z | > Z( α/2 )
Critical value Z(α/2) = Z( 0.1 /2 ) = ±
1.65
| a. |
The critical values for the test are ± 1.65. |

An online retailer claims the proportion of on-time deliveries is 85%. To test this claim, a random sample of deliveries are monitored and checked for on-time delivery status. Assume that the test statistic for this hypothesis test is 1.99. Since this is a two tailed hypothesis test, assume that the critical values for this hypothesis test are −1.96 and 1.96. Come to a decision for the hypothesis test and interpret your results with respect to the original claim. Select the...

The average amount of time it takes for couples to further communicate with each other after their first date has ended is 2.5 days with a standard deviation of 1.9 days. Is this average different for blind dates? A researcher interviewed 34 couples who had recently been on blind dates and found that they averaged 3.1 days to communicate with each other after the date was over. What can be concluded at the 5% level of significance? ho= ha= test...

A researcher claims that the proportion of college students who plan to participate in community service after graduation is greater than 35%. To test this claim, a survey asked 500 randomly selected college students if they planned to perform community service after graduation. Of those students, 195 indicated they planned to perform community service. The following is the setup m the following hypothesis test: H0:p=0.35 Ha:p>0.35 In this example, the p-value was determined to be 0.030. Come to a conclusion...

A cigarette manufacturer claims that the average nicotine content of their new brand XXX is at most 1.35 mg. It would be unwise to reject the manufacturer's claim without strong contradictory evidence. An appropriate problem formulation is to test A random sample of 100 brand XXX cigarettes are tested and the sample standard deviation and sample mean are found to be 0.07 mg and 1.361 mg, respectively.
