10.36 Aptitude tests should produce scores with a largeamount of variation so that an administrator candistinguish between persons with low aptitude andpersons with high aptitude. The standard test usedby a certain industry has been producing scoreswith a standard deviation of 5 points. A new test istried on 20 prospective employees and produces asample standard deviation of 8 points. Are scoresfrom the new test significantly more variable thanscores from the standard? Use a = 0.05.

incorrect Using traditional methods, it takes 97 hours to receive a basic flying license. A new license training method using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique with 110 students and observed that they had a mean of 98 hours. Assume the standard deviation is known to be 7. A level of significance of 0.01 will be used to determine if the technique performs differently than the traditional method. Find the value of the test statistic. Round your answer to 2 decimal places. Enter the value of the test statistic.

Aspirin is packed in 120 tab bottles with weight normally distributed with mean 600g and standard deviation 6g. Rejected bottles are those whose weight differs from the mean weight by 15g or more. That is, rejected bottles have weight either too small or too large. We want to find out how many bottles will be rejected from a daily production of 5000 bottles. 1,Do we have to calculate one z-score or two z-scores? 2. The negative z-score is 3. The positive z-score is 4.How many bottles, of the 5000, do we anticipate to have to reject?
This assignment is worth 1 points. The extra point will be added to your overall course grade. For example: if you receive an 88% in the course you can receive up to 1 point giving you a new score of 89%. The following rubric will be used. 0.25 point for drawing the normal distribution curve with the mean value labeled on the curve and the appropriate area shaded. 0.25 point for determining the value of the standard deviation of the sample mean. 0.5 point for finding the correct probability. All work must be shown in order to receive any credit. Please upload your completed assignment here. The length of time taken on the SAT for a group of students is normally distributed with a mean of 2.5 hours and a standard deviation of 0.25 hours. A sample size of n = 60 is drawn randomly from the population. Find the probability that the sample mean is between two hours and three hours.
AARP reported that the average senior citizens living at high altitudes claim their systolic blood pressure is lower than the average of 160. To test this claim, 16 senior citizens living at high altitudes were selected at random and their blood pressures checked. Their mean systolic pressure was 151, the standard deviation for the sample was 12. Do senior citizens living at high altitudes have significantly lower systolic blood pressure? Use the 0.05 level of significance.Remember to show your steps (including all relevant information) and explicitly verify that all assumptions of the procedure are satisfied. show the steps on how to solve it
Suppose the exam average in a class is 82% with a standard deviation of 6. What proportion of students scored below 88%? Round to two places.
Suppose a set of data has a sample mean of 112 and a sample standard deviation of 8.3. What is the z-score for the value 127.8? Round the z-score to two decimal places. Your Answer:
A researcher collects data that represents the average number of hours of sleep in the last two nights by 8 depressed patients and 9 non-depressed patients. The researcher is interested in whether the two groups reliably differ in the amount of sleep they get. Use Jamovi to calculate t-obt and the p value.
You want to know if a treated sample mean, M, is significantly different from some hypothesized mean, however, you do not have access to the popuation standard deviation, so you estimate it by computing the standard deviation of the sample. Which stats test do you run? a. z test for determining position of a score, x, in a population. b. one-sample t test. c. independent-samples t test. d. z test for determining the position of a mean, M, in a sampling distribution.
After 84 students at a particular university take a psychological evaluation, the sample mean score on the test is calculated to be 117 with a standard deviation of 44. We are interested in testing whether or not the mean score of the students at this university is different than the published population average of 112. Calculate the value of the test statistic and then use that to determine the appropriate p-value. 0.5952 0.2976 0.1488 0.8512 1.7024 0.1488 0.0744
