A manufacturer claims that the mean lifetime, p, of its light bulbs is 42 months. The standard deviation of these lifetimes is 5 months. Sixty bulbs are selectedat random, and their mean lifetime is found to be 44 months. Can we conclude, at the 0.01 level of significance, that the mean lifetime of light bulbs made bythis manufacturer differs from 42 months?Perform a two-tailed test. Then complete the parts below.Carry your intermediate computations to three or more decimal places, and round your responses as specified below. (If necessary, consult a list of formulas.)(a) State the null hypothesis H, and the alternative hypothesis H,.AzHo:H :(b) Determine the type of test statistic to use.OSO(Choose one)(c) Find the value of the test statistic. (Round to three or more decimal places.)(d) Find the two critical values. (Round to three or more decimal places.)and |(e) Can we conclude that the mean lifetime of light bulbs made by thismanufacturer differs from 42 months?O Yes ONoP.9.

Q1A Hi wonderful Bartleby team, I need help with this exercise, please provide answer and short explanation for all the answers. Thanks in advance. The last part of it is the sentence and the options are: -(Reject/ Fail to reject) the null hypothesis. There (Is / Not) sufficient evidence to support the claim that those treated with magnets have a greater mean reduction in pain than those given a sham treatment.
K The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject Ho when the level of significance is (a) a= 0.01, (b) a = 0.05, and (c) a = 0.10. P=0.0647 .. (a) Do you reject or fail to reject Ho at the 0.01 level of significance? OA. Reject Ho because the P-value, 0.0647, is greater than α=0.01. O B. Fail to reject Ho because the P-value, 0.0647, is less than α = 0.01. O C. Fail to reject Ho because the P-value, 0.0647, is greater than a = 0.01. OD. Reject Ho because the P-value, 0.0647, is less than a = 0.01. (b) Do you reject or fail to reject Ho at the 0.05 level of significance? OA. Fail to reject Ho because the P-value, 0.0647, is greater than α=0.05. OB. Reject Ho because the P-value, 0.0647, is greater than a = 0.05. OC. Reject Ho because the P-value, 0.0647, is less than a = 0.05. O D. Fail to reject Ho because the P-value, 0.0647, is less than a = 0.05. (c) Do you reject or fail to reject Ho at the 0.10 level of significance? 1
Food inspectors inspect samples of food products to see if they are safe. This can be thought of as a hypothesis test with the following hypotheses. H0: the food is safe Ha: the food is not safe The following is an example of what type of error? The sample suggests that the food is safe, but it actually is not safe. Choose one below a. type I b. type II c. not an error
