It has been claimed that 71% of all adults use their cell phones within an hour of going to bed.Believing this claimed value is too low, a researcher surveys a large random sample of adults andobtains a test statistic of 0.5. What will the P-value be?Between 0.01 and 0.05O There is not enough information available in the problem to determine the P-value.Larger than 0.10Between 0.05 and 0.10O Less than 0.01

A researcher claims that the amounts of acetaminophen in a certain brand of cold tablets have a mean different than the 600mg claimed by the manufacturer. Test this claim at the .01 significance level. The mean acetaminophen content for a random sample of n = 29 tablets is 597.9 mg with a standard deviation of 3.8 mg. What are the hypotheses? What is the test statistic? Is it a z or a t? Find the P-value for this test statistic. How does it compare to the significance level? On the normal curve, indicate the location of the test statistic and the p-value. (label them on the graph) Write a conclusion in statistical terms and relate it to the parameters of this problem.
A medical researcher wants to investigate the amount of time it takes for patients' headache pain to be relieved after taking a new prescription painkiller. She plans to use statistical methods to estimate the mean of the population of relief times. She believes that the population is normally distributed with a standard deviation of 15 minutes. How large a sample should she take to estimate the mean time to within 3 minutes with 93% confidence? ... Sample Size = Note:
A study was carried out to evaluate the safety of motorcycle helmets. 40 randomly selected helmets were subiected to a certain impact test and 20 were found to show no damage. The study claimed that the proportion of all helmets that would show no damage when tested in the prescribed manner is smaller than 62.5% (i.e. 5/8). With what confidence can this be claimed? a. 0.91 b. 0.93 c.0.95

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?
