Spatial perception is measured on a scale from 0 to 10. A group of 9thgrade students are tested for spatial perception. Suppose that a randomsample of 18 students gave an average spatial perception score of 6.00with a sample standard deviation of 1.815. Using a = 0.01, is the meanscore significantly different from 5?$4RO Yes, because t = 0.55 and this is greater than the critical value of 0.262.OYes, because t = 2.34 and this is greater than the critical value of 2.11.O No, because t = 0.55 and this is smaller than the critical value of 2.90.O No, because t = 2.34 and this is smaller than the critical value of 2.90.O No, because t = 0.55 and this is smaller than the critical value of 2.11.O No, because t = 2.34 and this is smaller than the critical value of 3.97.tv%♫Q Search or enter address5TA6MacBook ProYAⒸ&7+U*8-9)00

On a measure of running speed on a 100 meter dash, students received timed scores ranging from 12 seconds to 24 seconds. The distribution of running times is normative with a mean of 16 seconds. Transferring this ratio data to standard scores for comparison with the results of classes from other departments, the mean score is assigned a standard score of 100 with a standard deviation of 10. From this example, a standard score of 99 would mean the actual value in seconds for an individual would be about a. 16 b. 12 c. 19 d. 24
What raw score for age corresponds to a z- score of +4.50, given a mean of 12.0 years and a standard deviation of 4.0 years?

In a recent awards ceremony, the age of the winner for best actor was 36 and the age of the winner for best actress was 51. For all best actors, the mean age is 43.2 years and the standard deviation is 5.3 years. For all best actresses, the mean age is 38.6 years and the standard deviation is 11.4 years. (All ages are determined at the time of the awards ceremony.) Relative to Use z scores to compare the given values. their genders, who had the more extreme age when winning the award, the actor or the actress? Explain. ..... had the more extreme age. and the z score for the actress is z = the Since the z score for the actor is z= Score T (Round to two decimal places.)

Data from a government agency showed that the mean performance rating of employees is 87% with a standard deviation of 10%. Samples of 50 employees’ record were found to have a mean performance of 83. Based on this data, can we say that the mean performance of those employees were below the average at 0.05 level of significance?
Peak expiratory flow (PEF) is a measure of a patient’s ability to expel air from the lungs. Patients with asthma or other respiratory conditions often have restricted PEF. The mean PEF for children free of asthma is 306. An investigator conducts a study to investigate whether there is a difference in mean PEF in children with chronic bronchitis as compared to those without asthma or other respiratory conditions that often have restricted PEF. Data on PEF are collected and summarized below. Based on the data, is there statistical evidence of a lower mean PEF in children with chronic bronchitis as compared to those without? Run the appropriate test at a = 0.05. Group Number of Children Mean PEF Std Dev PEF Chronic Bronchitis 25 274 59 No Chronic Bronchitis 25 317 73
