In the third week of July, a random sample of 40 farming regions gave a sample mean of x = $6.88 per 100 pounds of watermelons. It is known that o = $1.92 per 100 pounds of watermelons. What can we assert with 98% confidence about the maximum error? (Reference: Agricultural Statistics, U.S. Department of Agriculture) %3D 2. (Example 2): At a test site in Great Sand Dunes National Park, Colorado, the prevailing wind did not change direction. However, the velocity did. Sixty wind speed readings gave an average velocity of x =1075 cm/sec. Basod on
An instructor for a test preparation course claims that the course will improve the test scores of students. The table shows the critical reading scores for 14 students the first two times they took the test. Before taking the test for the second time, the students took the instructor's course to try to improve their critical reading test scores. At a = 0.01, is there enough evidence to support the instructor's claim? Complete parts (a) through (f).
