Matlab function to solve an inequality that has a summation problem
on one side. I have to write a function that uses a while loop and
determines the biggest exponent value(k) in the summation out =
symsum(2^i,i,o,k) that exceeds the input n in the inequality out
> n so i need it to test the values of k from 1 on until out is
the closest over n it can be.
this assignment you will write two functions. The first...

Question 2 0/1 pts Solve the problem. A study of the amount of time it takes a mechanic to rebuild the transmission for a 2005 Chevrolet Cavalier shows that the mean is 8.4 hours and the standard deviation is 1.8 hours. If 40 mechanics are randomly selected, find the probability that their mean rebuild time is less than 8.9 hours. 0.4276 0.9756 0.9608 • 0.9589
