1.) Your statistics instructor claims that 60 percent of the students who take her Elementary Statistics class go through life feeling more enriched. For some reason that she can't quite figure out, most people don't believe her. You decide to check this out on your own. You randomly survey 64 of her past Elementary Statistics students and find that 34 feel more enriched as a result of her class. Now, what do you think?2.) A Nissan Motor Corporation advertisement read, "The average man's I.Q. is 107. The average brown trout's I.Q. is 4. So why can't man catch brown trout?" Suppose you believe that the brown trout's mean I.Q. is greater than four. You catch 12 brown trout. A fish psychologist determines the I.Q.s as follows: 5; 4; 7; 3; 6; 4; 5; 3; 6; 3; 8; 5. Conduct a hypothesis test of your belief."se a level of 5% unless otherwise stated. If the sample size is less than n=30, use a "t" distribution instead of "Z." Do not compute p-value for "t"distribution problems. Just compare the test value of "t" with the critical value corresponding to the given level." Basically, all work needs to be shown.
The length of the snake Vipera bertis (X), measured in centimeters, is assumed to be normally distrubuited with mean 63 and variance 22. The weight (Y) is measured on grams, can be calculated by using Y= -300 + 7x.
