mưoduction to nypoun A company that manufactures batteries used in electric cars is reporting that their newest model of battery has a mean lifetime, u, of 12 years. To test the company's claim, a competitor has selected 35 of these batteries at random. The mean lifetime of the sample is 10.8 years. Suppose the population standard deviation of these lifetimes is known to be 2.7 years. Is there enough evidence to reject the claim that the mean lifetime of the newest model is 12 years?

A statistics student randomly selected 45 packets of sugar and weighed the contents of each packet, getting a mean of 3.586 g and a standard deviation of 0.194 g. Test the claim that the weights of the sugar packets have a mean no longer equal to 3.5 g, as indicated on the label. Let "alpha" be 0.10 to test this claim. What is the decision/summary statement for this test?
Do male and female servers at Swank Bar work the same number of hours? A sample of 75 female servers worked an average of 27 hours per week, with a standard deviation of 2. A sample of 75 male servers worked an average of 21 hours per week, with a standard deviation of 5.Let μ1and μ2 represent the typical number of hours worked by all female and male servers at Swank Bar, respectively. Estimate with a 96% confidence level how many more hours female servers work. Round answers to the nearest hundredth._____< μ1−μ2<_____Which of the following does your data suggest?

The time necessary to complete the technical interview for the Google intership is normally distributed with a mean of sixty-three minutes, and a standard deviation of twelve minutes. Let the random variable X represent the number of minutes a randomly chosen student takes to complete the assessment. If a sample of three dozen students is taken, what is the standard deviation of the sample mean σX¯ and what is the probability that the sample mean would be 59 minutes or fewer?
(b) Perform a Z-test and find the p-value. Here is some information to help you with your Z-test. • The value of the test statistic is given by √n The p-value is the area under the curve to the right of the value of the test statistic. O One-tailed o Two-tailed Step 2: Enter the test statistic. (Round to 3 decimal places.) Step 3: Shade the area represented by the p- value. Step 4: Enter the p- value. (Round to 3 decimal places.) 0.3 0.2 0.1 (c) Based on your answer to part (b), choose what can be concluded, at the 0.05 level of significance, about the claim made by the studio. o Since the p-value is less than (or equal to) the level of significance, the null hypothesis is rejected. So, there is enough evidence to support the claim that the mean player rating is higher than 90. Since the p-value is less than (or equal to) the level of significance, the null hypothesis is not rejected. So, there is not enough evidence to support the claim that the mean player rating is higher than 90.…
Daily Driving The average number of miles a person drives per day is 24. A researcher wishes to see if people over age 60 drive less than24 miles per day. She selects a random sample of 25 drivers over the age of 60 and finds that the mean number of miles driven is 23.4. The population standard deviation is 4.1 miles. At=α0.01, is there sufficient evidence that those drivers over 60 years old drive less than 24 miles per day on average? Assume that the variable is normally distributed. Use the critical value method with tables. State the hypotheses and identify the claim with the correct hypothesis. :H0 =μ24 ▼not claim :H1 <μ24 ▼claim the hypothesis test is a ▼one-tailed test. Part 2 of 5 Find the critical value(s). Round the answer to at least two decimal places. If there is more than one critical value, separate them with commas. Critical value(s):
Facebook: A study showed that two years ago, the mean time spent per visit to Facebook was 19.8 minutes. Assume the standard deviation is o=10.0 minutes. Suppose that a simple random sample of 101 visits was selected this year and has a sample mean of x =22.8 minutes. A social scientist is interested to know whether the mean time of Facebook visits has increased. Use the a=0.10 level of significance and the P-value method with the TI-84 calculator.
