4. A lithium battery company claims that the lifetime of a type of battery that it manufactures is more than 250 hours. A surveyor firm wishing to determine whether the claim is justified measures the lifetimes of 24 of the company's batteries. The results are listed below: 271 230 198 275 282 225 284 219 253 216 262 288 236 291 253 224 264 295 211 252 294 243 272 268 Assuming the sample to be random, use the sign test to determine whether the company’s claim is justified at the 0.05 significance level.

The student body at many community colleges is considered a "commuter population". The following question was asked of the Student Affairs Office at one such college: "How far (one way) does the average community college student commute to college daily?" The office answered: "20.0 miles or less." The inquirer was not convinced of the truth of this and decided to test the statement. She took a random sample of 55 students and found a mean commuting distance of 21.5 miles. Test the statement made by the Students affairs Office at a significance level of 0.01. Assume that the population standard deviation is known to be 5.1 miles. Use the P-Value Method of Testing.In your work space below, you will need to have -1. The null hypothesis, Ho 2. The alternative hypothesis, H13. The test statistic 4. The type of test(left, right, two-tailed) and the p-value 5. The decision to accept Ho or reject Ho

A national internet service provider (ISP) claims that its broadband internet download speed is 100 megabits per second (Mbps) on average. To the contrary, there have recently been widespread reports that consumers are experiencing much slower download speeds from this ISP. A organization ogranization decided to investigate the issue. They took a random sample of 18 internet speeds from around the nation. The observations are given below. 95 101 88 110 87 91 88 103 91 83 94 83 87 87 87 82 97 100 Using a significance level of 0.05%, test the hypothesis that the average download speed is 100 Mbps, as advertised by the ISP. Assume that the distribution of all broadband internet download speed measurements from this ISP is approximately normally distributed. Use the critical value method. Determine the critical value(s) for this hypothesis test. Round the solution(s) to four decimal places. If more than one critical value exists, enter the solutions using a comma-separated…
