A factory in Louisville, Kentucky, produces baseball bats. The diameter of the bat should be 9 cm. Out of 371 samples, the sample mean is 8.85 cm with a sample standard deviation of 0.55 cm. Give a 85% confidence interval for the mean diameter (i.e., the lower and upper bound of the confidence interval). number (rtol=0.01, atol=0.0001) Lyb number (rtol=0.01, atol=0.0001) The manager wants to know the 99% confidence interval to be within at most +/- 0.05 cm. How many samples would you (as the junior engineer) need to take to satisfy the manager's desire for precision? number (rtol=0.01, atol=0.0001)

The gasoline consumption projected for a car model is 13 km / l. After the launch of the vehicle, a specialized magazine carried out a test that showed 1300 cars, an average consumption of 12.3 km / l. The manufacturer claims that the standard deviation of consumption is 0.5 km / l. test the hypothesis that consumption is at least 13km / l.
The mean consumption of water per household in a city was 1239 cubic feet per month Due to a water shortage because of a drought, the city council campaigned for water use conservation by households. A few months after the campaign was started, the mean consumption of water for a sample of 92 househoids was found to be 1157 cubic feet per month. The population standard deviation is given to be 251 cubic feet a. Find the p-value for the hypothesis test that the mean consumption of water per household has decreased due to the campaipn by the city council. Would you reject the null hypothesis at a = 0.025? Round your answer to four decimal places. pvalue =i We b. Make the test of part a using the critical-value approach and a = 0.025. Round your answer for z to two decimal places. Zoberved We We conclude that the mean consumption of water per household has due to the campaign by the city council.
The ages of registered voters in Smith County are normally distributed with a population standard deviation of 3 years and an unknown population mean.

The average content of certain harmful substances downstream of the Han River is 0.6 mg/l, and the standard deviation for this is known to be 0.1 mg/l. As a result of the water quality improvement campaign for one year, we would like to find out whether the specific harmful substances have decreased. In order to collect 100 samples and reduce them to 95% confidence level, the average of the sample should be obtained below what value?
The mean life expectancy in the US pop. is currently 81.1 years with a standard deviation of 15.9. A researcher examined the age of death of 70 people in Florida hospitals and the mean was 85.2 yrs. He runs a 2tailed test with a=.05 to see if FL has significantly different life expectancy to the overall US pop. Calculate the standard error, z statistic and critical z values from this information.
A researcher collected sample data for 10middle-aged women. The sample had a mean serum cholesterol level (measured in milligrams per one hundred milliliters) of 192.5, with a standard deviation of 9. Assuming that serum cholesterol levels for middle-aged women are normally distributed, find a 95% confidence interval for the mean serum cholesterol level of all women in this age group.

A car manufacture produces a new car that advertises an average of 30 MPG. The distribution of MPG of cars is normally distributed. The manufacturer will test 30 cars off the assembly line to find a confidence interval of the average MPG of their new vehicle to determine if it is close to 30. The average MPG of the 30 cars is 31.2 gallons with a standard deviation of 2 gallons. Find a 95% confidence interval for the average MPG of the new vehicle. (30.45, 31.95) (30.48, 31.92) O (31.18, 31.22) O The sample size is too small to compute a confidence interval.
Does it take less time for seeds to germinate if they are near rock music that is continuously playing compared to being near classical music? The 43 seeds that were exposed to rock music took an average of 27 days to germinate. The standard deviation was 10 days.

A city planner wants to estimate the average monthly residential water usage in the city. He selected a random sample of 42 households from the city, which gave the mean water usage to be 3409.30 gallons over a one-month period. Based on earlier data, the population standard deviation of the monthly residential water usage in this city is 387.90 gallons. Make a 97% confidence interval for the average monthly residential water usage for all households in this city.
