A producer of televisions claims that his product will last at least 10 years on average. A sample of 40 is taken and the mean and standard deviation are found. The test statistic is calculated to be 1.756. Using a 5% level, the conclusion would be a. there is insufficient evidence for the producer’s claim to be considered correct b. there is sufficient evidence for the producer’s claim to be considered incorrect c. None of the above d. there is sufficient evidence for the producer’s claim to be considered correct
You were told that the mean daily cost of a hotel room in downtown St. Louis is $120. You will be needing to rent a hotel room there in the near future and you want to find the best rate. You randomly select a sample of 18 hotel rooms and find that the average cost is $121.33 with a standard deviation of $18.046. At the α = 0.05 significance level, determine if there is enough evidence to reject the claim. What is the decision for this hypothesis test?

A manufacturer considers his production process to be out of control when defects exceed 4%. In a random sample of 146 items, the defect rate is 8.3% but the manager claims that this is only a sample fluctuation and production is not really out of control. At the 5% level of significance, use the p-value method to test the manager's claim. Enter the p-value. (Round your answer to nearest thousandth.) When using tables to find a tight range for the p-value, enter one of the boundaries of the interval (not 0 or 1) found using the tables.

Because schools in areas affected by these natural disasters were disproportionately low performing schools, many students affected were not only forced to switch schools, but also ended up switching to a higher quality school. Sacerdote finds initial declines in test scores (likely due to the shock of displacement), but “by the third and fourth years after the disaster, evacuees displaced [by these natural disasters] see a 0.18 standard deviation improvement in scores.” Sacerdote also finds that the improvements observed were “concentrated among students initially in the lowest quintiles of the test score distribution.” 1. Define the outcome (Y), the endogenous regressor (X), and the instrument (Z) in the context of this study.2. Is this instrument relevant? Explain why or why not.3. Is this instrument exogenous?

Dr. Sylvester Stallone is a circadian rhythms researcher and believes sleep affects memory. Having collected data on a large number of subjects who are getting the recommended amount of sleep, he knows the mean digit span of this population is 5.6 digits. To test his hypothesis, he measures the digit span of 15 volunteers randomly selected from the population, after depriving them of one night’s sleep. The results show a mean (X bar) of 4.1 and a standard deviation of (s) 1.4. a. What does Dr. Stallone conclude, using and alpha of 0.05 (two tailed)? b. If appropriate, calculate the size of effect and provide an interpretation of the value?
