QUESTION 5 The television picture tubes of manufacturer Sumsun have a mean lifetime of 7 years and a standard deviation of 0.8 year, while those of manufacturer Fillip have a mean lifetime of 6.0 years and a standard deviation of 0.7 year. A random sample of 64 tubes is taken from manufacturer Sumsun while a random sample of 49 tubes is taken from manufacturer Fillip. What is the probability that the difference between the mean lifetimes of the television picture tubes from the two manufacturers is not more than 0.8 year?

QUESTION 22 "A psychotherapist investigating whether clients revealed more information while sitting in an easy chair or when lying down on a couh, so she randomly assignd 15 clients to each condition. The third session for each client was videotaped, and an independent observer counted the client?s disclosures and the two groups were then compared. They find that clients who sit reveal an average of 3.04 disclosures, variance = 8.92. While the clients who lay down share an average of 4.46 disclosures, with a sample variance = 9.05. psychotherapist would observe given this data? (Be sure to round your response a sample would be the test statistic the with What to the second decimal place). "

QUESTION 1 A health researcher read that a 150-pound college-aged, male can burn an average of 530 calories per hour playing tennis with a standard deviation of 25 calories. 40 college-aged males were randomly selected at a commuter school and the mean number of calories burned per hour playing tennis was 540 calories. Do college-aged male tennis players at the commuter school burn more calories per hour than the college-aged, male tennis player population? Test with a 0.05 significance level. What are the hypotheses? Null and Alternate

Question 6 Ho Select an answer 0² The mean age when smokers first start is 13 years old with a population standard deviation of 2 years. A researcher thinks tha: smoking age has significantly changed since the invention of ENDS-electronic nicotine delivery systems. A survey of smokers of this generation was done to see if the mean age has changed. The sample of 34 smokers found that their mean starting age was 12.3 years old. Do the data support the claim at the 10% significance level? What are the correct hypotheses? Н1 Ba Te HD SIX P s² Critical Values = ± years years find the following: (Give answer to at least 4 decimal places) (Give answer to at least 4 decimal places) Based on the above we choose to Select an answer The correct summary would be: Select an answer mean age smokers first start is different than 13. that the claim that the
King Tut was an ancient Egyptian ruler whose tomb was discovered and opened in 1923 . Legend has it that the archaeologists who opened the tomb were subject to a "mummy's curse," which would shorten their life spans. A team of scientists conducted an investigation of the mummy's curse. They reported that the 24 people exposed to the curse had a mean life span of 71.1 years with a standard deviation of 11.6 years, while a sample of 12 Westerners in Egypt at the time who were not exposed to the curse had a mean life span of 77.7 years with a standard deviation of 13.9 years. Assume that the populations are approximately normal. Can you conclude that the mean life span of those exposed to the mummy's curse differs from the mean life span of those not exposed? Let μ1 denote the mean life span of those exposed to the mummy's curse and μ2 denote the mean life span of those not exposed. Use the =α0.01 level and the P -value method with the TI-84 Plus calculator. do we…
Question 6 "An electrical firm produces light bulbs that have a length of life that is approximately normally distributed with a mean of 660 hours and a population standard deviation of 25 hours. A new version of light bulbs is being produced and is assumed to be better than the previous version. To test this claim, a random sample of 92 new light bulbs are tested. Would you buy the new version of the light bulb or would you buy the older version if the random sample showed an average of 870 hours? Use a 0.05 level of significance." I will buy the older version until there is sufficient evidence to do otherwise. B I will buy the new version. C I will certainly buy the older version because I am 100% sure it is better. There is no sufficient data to make a sound conclusion.
