In 2003, the Accreditation Council for Graduate Medical Education (ACGME) implemented new rules limiting work hours for all residents. A key component of these rules is that residents should work no more than 80 hours per week. The following is the number of weekly hours worked in 2017 by a sample of residents at the Tidelands Medical Center.
| 87 | 83 | 83 | 88 | 79 | 83 | 90 | 87 | 90 | 83 | 74 | 80 |
- What is the point estimate of the population mean? (Round your answer to 2 decimal places.)
- Develop a 98% confidence interval for the population mean. (Use t Distribution Table.) (Round your answers to 2 decimal places.)
- Is the company’s claim that the “typical customer” spends $80 per month reasonable?

is (greater than. Less than or equal to)
the significance level. There (is not. Is)
sufficient evidence that the mean time interval has charged
Listed below are time intervals (min) between eruptions of a geyser. Assume that the "recent" times are within the past few years, the "past" times are from around 20 years ago, and that the two samples are independent simple random samples selected from normally distributed...

Please follow the steps of hypothesis testing, including
identifying the alternative and null hypothesis, calculating the
test statistic, finding the p-value, and making a conclusions about
the null hypothesis and a final conclusion that addresses the
original claim. Use a significance level of 0.10. Is the conclusion
affected by whether the significance level is 0.10 or 0.01?

Use Table 8.1, a computer, or a calculator to answer the following. Suppose a candidate for public office is favored by only 47% of the voters. If a sample survey randomly selects 2,500 voters, the percentage in the sample who favor the candidate can be thought of as a measurement from a normal curve with a mean of 47% and a standard deviation of 1%. Based on this information, how often (as a %) would such a survey show that...
