Students were asked to look at their hands and decide which finger on their hands is longer: the index finger or the ring finger. The results of the survey are in the following table.

males

females

Index finger longer

27

48

Ring finger longer

69

99

96

147
  1. Interpret, in terms a non-statistics person would understand, your 90% confidence interval, explaining what it tells us about the proportions of males and females whose ring finger is longer than their index finger.
  2. Based on your confidence interval, could the population proportion of all males whose ring finger is longer be equal to the population proportion for all females? (Please explain, don’t just say yes or no.)
  3. Based on your confidence interval, could the population proportion of all males whose ring finger is longer be 0.10 or 10% larger than the population proportion for all females? (Please explain, don’t just say yes or no.)
  4. Based on your confidence interval, could the population proportion of all males whose ring finger is longer be 0.10 or 10% smaller than the population proportion for all females? (Please explain, don’t just say yes or no.)

A study was conducted in which students were asked to estimate the number of calories in a cheeseburger. One group was asked to do this after thinking about a​ calorie-laden cheesecake. A second group was asked to do this after thinking about an organic fruit salad. The mean number of calories estimated was 771 for the group that thought about the cheesecake and 1008 for the group that thought about the organic fruit salad. Suppose that the study was based...

Women’s hands are 6.9 inches on average (from the tip of the middle finger to the heel of the hand). The standard deviation is 0.34 inches. Assume that hand length is normally distributed. A.) What is the probability that a woman would have a hand length longer than 7.58 inches? Show your work. Start by finding the z-score for 7.58 and then use what you know about the normal distribution to find the probability. B.) What is the probability that...

Students in a school were asked to participate in a study of the effects of a new teaching method on reading skills of 10th graders. To determine the effectiveness of the new method, a reading test was given to each student before applying the new method (pre-test). Another test was given to the same students after applying the new method (post-test). Experts consider that a good measure of improvement is given by the following formula: Improvement=20(Post-test score)- 10(Pre-test score). That...

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 a​ professor, 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 21.8 with a standard deviation...
