The heights of a random sample of 50 college students showed a mean of 167.4 centimeters and a standard deviation of 6.9 centimeters. (a) construct a 98% confidence interval for the mean height of all college students. (b) what can we assert with 98% confidence about the possible size of our error if we estimate the mean height of all college students to be 167.4 centimeters?

Drag the tiles to the table. the tiles can be used more than once. nd g(x) = 2x + 5 model a similar situation. find the values of f(x) and g(x) let's say that the functions f(x for the given values of x. fix)=5(4) * g(x) = 2x+5
