Suppose that, at the end of last semester, Marie gave her introductory statistics class a final exam. After grading these exams, she created a histogram illustrating the distribution of exam scores for the 70 students in the class. Each of the bars in this histogram includes only the left endpoint of the interval, except for the bar representing scores between 90 and 100 points, which also includes the right endpoint. What percentage of students scored between 60 and 80 points on the exam? Round your answer to the nearest tenth of a percent. Number of students who scored at least 80 points = students Percentage of students who scored between 60 and 80 points = %

Entry to a certain University is determined by a national test. The scores on this test are normally distributed with a mean of 500 and a standard deviation of 100. Tom wants to be admitted to this university and he knows that he must score better than at least 80% of the students who took the test. Tom takes the test and scores 595. Will he be admitted to this university?
Atli believes that there is a linear relationship between the temperature in Reykjavík and the sale of mittens in his shop. He signs down the temperature in Reykjavík 7 random days and bears It compares with total sales of mittens (in krónur) the same day. The temperature measured to Average 4 degrees the days of Atli measured, with the standard deviation of 3 degrees. The total settlement sales turned out on average 28400 krónur with the standard deviation of ISK 4920. The correlation Between the mitty sales and temperature measured -0.68. How much does the mitten change when the temperature rises by one degree according to the model? Sales decreased by ISK 1115.2. The sale increases by ISK 1115.2. Sales decreased by ISK 235.7. Sales do not change. Atli wants to examine whether it is actually correlated between the mitty sales and temperature. He performs The bilateral hypothesis test and the test size in his hypothesis test is -2.07. Which resolution does he draw? He cannot…

2. (MMC 6.43). The Survey of Study Habits and Attitudes (SSHA) is a psychological test that measures the motivation, attitude toward school, and study habits of students. Each score ranges from 0 to 200. The mean attitude score for U.S. college students is about 110, and the standard deviation is about 25. A teacher who suspects that older students have better attitudes toward school gives the SSHA to 25 students who are at least 30 years of age. Their mean score is = 118.3. a. Assuming that o = 25 for the population of older students, carry out a test of Họ: H = Ha:u > 110 Report the P-value of your test and state your conclusion clearly. = 110 b.
