← A boat capsized and sank in a lake. Based on an assumption of a mean weight of 146 lb, the boat was rated to carry 70 passengers (so the load limit was 10,220 lb). After the boat sank, the assumed mean weight for similar boats was changed from 146 lb to 174 lb Complete parts a and b below. a. Assume that a similar boat is loaded with 70 passengers, and assume that the weights of people are normally distributed with a mean of 177.5 lb and a standard deviation of 38.1 lb. Find the probability that the boat is overloaded because the 70 passengers have a mean weight greater than 146 lb The probability is (Round to four decimal places as needed)
Executives of a supermarket chain are interested in the amount of time that customers spend in the stores during shopping trips. The mean shopping time, μ, spent by customers at the supermarkets has been reported to be 38 minutes, but executives have good reason to believe that u is different from 38 minutes. The executives hire a statistical consultant and ask her to perform a statistical test. To perform her statistical test, the consultant collects a random sample of shopping times at the supermarkets. She computes the mean of these times to be 44 minutes and the standard deviation of the times to be 10 minutes. Based on this information, complete the parts below. (a) what are the null hypothesis Ho and the alternative hypothesis H₁ that should be used for the test? Ho H₁ :0 (b) Suppose that the consultant decides not to reject the null hypothesis. What sort of error might she be making? (Choose one) ▼ (c) Suppose the true mean shopping time spent by customers at the supermarkets is…

Market Researchers have become more interested in the potential of social networking sites. Butthey need to understand the demographics of social networking users. A recent survey showed that22 of the 30 respondents who reported earning less than $30,000 per year said that they weresocial networking users. The mean salary of the 22 respondents was $21,500 with a standarddeviation of $200. On the other hand, 20 of the 30 respondents who reported earning more than$70,000 per year said that they were social networking users. The mean salary of the 20respondents was $90,000 with a standard deviation of $300. (a) Is there is enough evidence to infer that those who reported earning less than $30,000 per yearare more likely to be social networking users? Assume that the level of significance is 2.5%. (b) Estimate with 98% confidence the variance of salaries of the entire population of social networkusers earning more than $70,000 per year
