An observational study of teams fishing for the red spiny lobster in a certain body of water was conducted and the results published in a science magazine. One of the variables of interest was the average distance separating traps - called "trap spacing" - deployed by the same team of fishermen. Trap spacing measurements (in meters) for a sample of seven teams of fishermen are shown the accompanying table. Of interest is the mean trap spacing for the population of red spiny lobster fishermen fishing in this body of water. Complete parts a through f below. Click the icon to view the trap spacing data. a. Identify the target parameter for this study. The target parameter for this study is b. Compute a point estimate of the target parameter. (Round to two decimal places as needed.) c. What is the problem with using the normal (z) statistic to find a confidence interval for the target parameter? OA. The point estimate is too large to determine an accurate z-statistic. OB. The sample is small and the trap spacing population has unknown distribution and standard deviation. OC. The point estimate is too large to determine an accurate critical value. O D. The z-statistic is used for confidence intervals for proportions, not means. d. Find a 95% confidence interval for the target parameter. (Round to one decimal place as needed.) e. Give a practical interpretation of the interval, part d. Choose the correct answer below. OA. One can be 95% confident the true mean trap spacing distance is one of the end points of the above interval. OB. One can be 95% confident the true mean trap spacing distance lies within the above interval. OC. There is a 95% probability that the true mean trap spacing distance is the mean of the interval. OD. One can be 95% confident the true mean trap spacing distance lies at the mean of the above interval. Trap Spacing Data 91 100 106 Print 93 83 Done 69 84

This is only one question

Which set of data would probably show a strong positive linear correlation? a) the number of defective light bulbs produced and the time of the day when they were manufactured b) marks on a history test and the heights of the students c) the colour of cars sold and the annual income of the car buyers d) the height of corn in a field and the amount of precipitation during the growing season

A physical therapist wanted to know whether the mean step pulse of men was less than the mean step pulse of women. She randomly selected 59 men and 73 women to participate in the study. Each subject was required to step up and down a 6-inch platform. The pulse of each subject was then recorded. The following results were obtained. SE Mean 1.5 1.7 SIDev 11.2 Mean 112.7 Men Women 99% CI for mu Men - mu Women -11.89, 0.09) T-Test mu Men mu Women (vs<) T= -2.61 P=0.0051 DF 129 59 73 118.6 14.8 Two sample T for Men vs Women State the researcher's condlusion. Which of the following is correct? O A Reject Ha, there is sufficient evidence to condlude that the mean step pulse of men was less than the mean step pulse of women the mean step pulse of women O B. Reject Ha, there is not sufficient evidence to condlude that the mean step pulse of men was less OC. Fail to reject Ho, there is sufficient evidence to conclude that the mean step pulse of men was less than the mean steg pulse of women O D.…
