Suppose you collect data on people’s height from a sample of 100 people. The average height in the sample is 66, and the standard deviation of the sample meanis 3 inches. Calculate the 95% confidence interval for the average height in the population At the 12% significance level, test the hypothesis that the average height in the population is 69 inches. Use the four steps we discussed in class. Calculate the p-value for the hypothesis that the average height in...

A rock is thrown upward from a bridge that is 83 feet above a road. The rock reaches its maximum height above the road 0.61 seconds after it is thrown and contacts the road 3.87 seconds after it was thrown.

A rock is thrown upward from a bridge that is 83 feet above a road. The rock reaches its maximum height above the road 0.61 seconds after it is thrown and contacts the road 3.87 seconds after it was thrown. Write a function f that determines the rock's height above the road (in feet) in terms of the number of seconds tt since the rock was thrown. THE FUNCTION MUST BE IN THE FORMAT f(t)=c⋅(t−t_1)(t−t_2) for fixed numbers c,...
