Chapter 1, Problem 37P

The velocity v and the falling distance d as a function of time of a skydiver that experience the air resistance can be approximated by:

and d ( t ) = m k ln c o s h k g m t

where k = 0.24 kg/in is a constant, in is the skydiver mass, g = 9.81 m/s2 is the acceleration due to gravity, and s is the time in seconds since the skydiver starts falling. Determine the velocity and the falling distance at t=8 s for a 95-kg skydiver

v ( t ) = m g k tanh k g m t

In a survey of 2193 adults in a recent year, 1233 say they have made a New Year's resolution. Construct 90% and 95% confidence intervals for the population proportion. Interpret the results and compare the widths of the confidence intervals. The 90% confidence interval for the population proportion p is (Round to three decimal places as needed.) J.D) .
Let p be the population proportion for the following condition. Find the point estimates for p and q. In a survey of 1143 adults from country A, 317 said that they were not confident that the food they eat in country A is safe. The point estimate for p, p, is (Round to three decimal places as needed.) ...
(c) Because logistic regression predicts probabilities of outcomes, observations used to build a logistic regression model need not be independent. A. false: all observations must be independent B. true C. false: only observations with the same outcome need to be independent I ANSWERED: A. false: all observations must be independent.  (This was marked wrong but I have no idea why. Isn't this a basic assumption of logistic regression)
