a) Explain the difference between these two statistical cocepts: "Independent events" and "Mutually Exclusive events". Your answer should be in words (no diagrams/graphs/forumulae) and should be a mar- imum of two sentences long. b) A 95% confidence interval for a population mean is calculated as (4.36,9.21). A student interprets this as: "There is a 95% probability that the population mean is between 4.36 and 9.21." Is the student's interpretation correct? Answer YES' or NO'. • If YES, explain why the interpretation is correct. • If 'NO', explain what is wrong with the student's answer and then explain what the correct interpretation of the '95%' is. c) Studies have shown that there is a high positive correlation between height and weight. Sam is tall, over 1.9m (which is 6 ft 2 inches). Does that imply that he is heavier than average? Justify.

1. A company surveyed its employees to determine what the new daily meal allotment dollar amount should be. Of the 159 employees, 94 responded. Pat’s supervisor asked what the recommended dollar amount should be. Pat could take the mean of the 94 responses or calculate a confidence interval about the mean using those 94 responses. Which action of the two (don’t go outside these choices) would give the supervisor a better idea of what the true mean is, and why?

According to a Field Poll, 263 out of 569 of California adults feel that "education and our schools" is one of the top issues facing California. We wish to construct a 90% confidence interval for the true proportion of California adults who feel that education and the schools is one of the top issues facing California. The error bound is ___________ rounded to 4 decimal places.
What if we're able to use a normal model. To construct a 95% Confidence Interval, we use the following formula: p hat ± ME for 95% CI If p hat = 0.38 and ME for 95% CI = 0.096, what is CI? Keep the numbers in 3 decimal places. Put the two numbers in ( ) and use a comma, then a space between the two numbers.
