Two researchers conducted a study in which two groups of students were asked to answer 42 trivia questions from a board game. The students in group 1 were asked to spend 5 minutes thinking about what it would mean to be aprofessor, while the students in group 2 were asked to think about soccer hooligans. These pretest thoughts are a form of priming The 200 students in group 1 had a mean score of 24.8 with a standard deviation of 4 8 while the200 students in group 2 had a mean score of 18 with a standard deviation of 3.1.

For a random sample of 36 data pairs, the sample mean of the differences was 0.77. The sample standard deviation of the differences was 2. At the 5% level of significance, test the claim that the population mean of the differences is different from 0.
In an examination, the marks are normally distributed with mean of 60.7 and standard deviation of 12.3 The board awards distinctions to the best 10% of the candidates. What is the least mark a candidate will need to get distinction?
Last fall, a sample of n = 36 freshmen was selected to participate in a new 4-hour training program designed to improve study skills. To evaluate the effectiveness of the new program, the sample was compared with the rest of the freshman class. All freshmen must take the same English Language Skills course, and the mean score on the final exam for the entire freshman class was µ = 74. The students in the new program had a mean score of M = 79.4 with a standard deviation of s = 18. Can the college conclude that the students in the new program are significantly different from the rest of the freshman class? Use a two- tailed test with α = .05.
Bone mineral density (BMD) is a measure of bone strength. Studies show that BMD declines after age 45. The impact of exercise may increase BMD. A random sample of 59 women between the ages of 41 and 45 with no major health problems were studied. The women were classified into one of two groups based upon their level of exercise activity: walking women and sedentary women. The 39 women who walked regularly had a mean BMD of 5.96 with a standard deviation of 1.22. The 20 women who are sedentary had a mean BMD of 4.41 with a standard deviation of 1.02. Which of the following inference procedures could be used to estimate the difference in the mean BMD for these two types of women
A sample of 20 observation is selected from a normal population, the sample mean is 2.78 and the standard deviation is 0.83. Another sample of 18 observation was selected and the mean is 2.63 with standard deviation of 0.75. Test at 0.01 level of significance. What is the computed value and decision.
A survey among freshmen at a certain university revealed that the number of hours spent studying the week before final exams was normally distributed with mean 25 and standard deviation 9. Between what two values are the middle 80% of the hours spent studying?
Suppose that shoe sizes of American women have a bell-shaped distribution with a mean of 8.4 and a standard deviation of 1.51. Using the empirical rule, what percentage of American women have shoe sizes that are between 5.38 and 11.42?
A particular IQ test is standardized to a Normal model, with a mean of 80 and a standard deviation of 8. A group of 8,000 people had participated in a study based on IQ. Using the Empirical rule determine about how many of them should have IQ scores more than 72?
The determination of copper in a sea water sample gave a mean value of 77.81 ug/L and a standard deviation s, of 1.74 µg/L. How many samples must be analyzed to obtain a relative standard deviation (RSD) of 1.7% in the results at the 95% confidence level? (t at the 95% confidence level = 1.96)
In 16 women with diabetes, the morning blood sugar mean was 49.4 with a standard deviation of 24.0. In normal healthy women, the mean was 47.0. From the sample information, can we conclude that the blood sugar mean in women with rheumatoid arthritis is greater than that in normal women? Assume a significance level of 0.05.
A researcher wanted to know whether losing one night sleep can affect problem solving. A sample of n = 25 college students was given a problem-solving task at noon on one day and again at noon on the following day. The students were not permitted any sleep between the two tests. For each student, the difference between the first and the second score was recorded: MD = 5 and standard deviation of the difference score was s = 10. Do the data indicate a significant change in problem solving ability? Use a two-tailed test with α = .01. The alternative hypothesis in words is Group of answer choices Problem solving ability improves after losing on night sleep Problem solving ability is reduced after losing one night of sleep There is no significant difference in problem solving ability between the two conditions: before and after losing one night of sleep There is a significant difference in problem solving ability between the two conditions: before and after losing one night of…
