The World Health Organization reports that the distribution of ages at time of death in the United States has a mean u of 79.8 years and a standard deviation ơ of 15.5 years, based on death certificates. The distribution of ages at time of death is obviously left-skewed (thankfully, few people die young and most die old). Researchers plan to take a random sample of 100 American death certificates. (a) What are the mean and standard deviation of the sampling distribution of the mean age at death, x, for samples of 100 American death certificates? (Enter your answer rounded to two decimal places.) mean: years standard deviation years (b) Choose the correct explanation why the sampling distribution of is approximately Normal O The sampling distribution of is approximately Normal because the 100 death certificates represent a O The sampling distribution of is approximately Normal because the 100 death certificates do not represent a The Central Limit Theorem says that the sampling distribution of a mean does not have an approximately Normal Normal population. Normal population. distribution even if the population is not Norma The Central Limit Theorem says that the sampling distribution of a mean has an approximately Norm.l distribution even if the population is not Normal, (as long as the sample size is large enough) Scroll (c) What is the probability that the mean age at time of death in a random sample of 100 American death certificates will be less than 78 years?

A report states that the cost of repairing a hybrid vehicle is falling even while typical repairs on conventional vehicles are getting more expensive. The most common hybrid repair, replacing the hybrid inverter assembly, had a mean repair cost of $ 3 comma 927 3,927 in 2012. Industry experts suspect that the cost will continue to decrease given the increase in the number of technicians who have gained expertise on fixing gas-electric engines in recent months. Suppose a sample of 100 100 hybrid inverter assembly repairs completed in the last month was selected. The sample mean repair cost was $ 3 comma 850 3,850 with the sample standard deviation of $ 300 300. Complete parts (a) and(b) below. a. Is there evidence that the population mean cost is less than $ 3 comma 927 3,927? (Use a 0.10 0.10 level ofsignificance.) State the null and alternative hypotheses. H0: mu μ greater than or equals ≥ $ 3927 3927 H1: mu μ less than < $ 3927 3927 (Type integers or decimals.) Find the test statistic for this hypothesis test. t Subscript STAT tSTAT equals = nothing(Round to two decimal places as needed.) The critical value(s) for the test statistic is(are) nothing . (Round to two decimal places as needed. Use a comma to separate answers as needed.) Is there sufficient evidence to reject the null hypothesis using alpha α equals = 0.10 0.10? A. Do not reject Do not reject the null hypothesis. There is insufficient insufficient evidence at the 0.10 0.10 level of significance that the population mean cost is less than $ 3 comma 927 3,927. B. Reject Reject the null hypothesis. There is sufficient sufficient evidence at the 0.10 0.10 level of significance that the population mean cost is greater than $ 3 comma 927 3,927. C. Reject Reject the null hypothesis. There is sufficient sufficient evidence at the 0.10 0.10 level of significance that the population mean cost is less than $ 3 comma 927 3,927. D. Do not reject Do not reject the null hypothesis. There is insufficient insufficient evidence at the 0.10 0.10 level of significance that the population mean cost is greater than $ 3 comma 927 3,927. b.

A survey conducted by the American Automobile Association showed that a family of four spends an average of $215.60 per day while on vacation. Suppose a sample of 64 families of four vacationing at Niagara Falls resulted in a sample mean of $252.45 per day and a sample standard deviation of $77.50. a. Develop a 95% confidence interval estimate of the mean amount spent per day by a family of four visiting Niagara Falls (to 2 decimals). ( , ) b. Based on the confidence interval from part (a), does it appear that the population mean amount spent per day by families visiting Niagara Falls differs from the mean reported by the American Automobile Association?

You are playing the duck pond game at the carnival! There are 20 ducks in the pond. Five of the ducks have blue dots on their bellies. You win if you pick up a duck that has a blue dot. You can play one round for $1 or four rounds for $3. In each round you will pick a duck out of the pond and see if it has a blue dot on its belly. If you win you get a prize. After that you place the duck back in the pond, close your eyes, and the worker moves all of the ducks around. If you play the duck pond game four times, what is the probability that you will win three of the times? (Hint: How many possible outcomes are there for this experiment?)
