The manufacturer claims that your new car gets 26 mpg on the highway. You suspect that the mpg is more for your car. The 55 trips on the highway that you took averaged 27.5 mpg and the standard deviation for these 55 trips was 5.9 mpg. What can be concluded at the a = 0.05 level of significance? a. For this study, we should use (Select an answer b. The null and alternative hypotheses would be: Ho: ? Select an answer H1: Select an answer v C. The test statistic (please show your answer to 3 decimal places.) d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is (? a f. Based on this, we should (Select an answer v the null hypothesis. g. Thus, the final conclusion is that ... O The data suggest that the population mean is not significantly more than 26 at a = 0.05, so there is statistically insignificant evidence to conclude that the population mean mpg for your car on the highway is more than 26. O The data suggest that the populaton mean is significantly more than 26 at a = 0.05, so there is statistically significant evidence to conclude that the population mean mpg for your car on the highway is more than 26. O The data suggest that the sample mean is not significantly more than 26 at a = 0.05, so there is statistically insignificant evidence to conclude that the sample mean mpg for your car on the highway is more than 27.5. h. Interpret the p-value in the context of the study. OIf the population mean mpg for your car on the highway is 26 and if you take another 55 trips on the highway then there would be a 3.23751601% chance that the sample mean mpg for these 55 trips would be greater than 27.5. There is a 3.23751601% chance of a Type I error.

A man was at one corner of a 1656 square yard rectangular field. He then ran to the furthest corner, as shown in the diagram. If the length L of the field is 3 yards longer than three times the width W, then how far did the man run? Find both the exact solution and an approximate solution.

I need help with the second part of this problem. Where the 8, 9, and 11 is

Solve the following by setting up the proper equations to describe the facts given and then carrying out the mathematical calculations to solve for the unknown variable(s). Let x represent length and y represent width. Enter your answer in (x, y) format. The length of a rectangle is 3 times the width. The difference between the length and width is 14 feet. Determine the rectangle's length and width.

I asked this question earlier but was still very confused on how to solve the problem. If you can please write out step by step and show exactly how to solve this problem it would help give me a more clear visual way on how to solve this. Thank you. QUESTION:
