Need help to solve homework excercise from chapter 6.6 of triola stats. Please also provide explanation using technology either TI-84 or statcrunch.

In a study of433,231 cell phoneusers, it was found that80 developed cancer of the brain or nervous system. Assuming that cell phones have noeffect, there is a0.000223 probability of a person developing cancer of the brain or nervous system. We therefore expect about97 cases of such cancer in a group of 433,231 people. Estimate the probability of80 or fewer cases of such cancer in a group of433,231 people. What do these results suggest about media reports that cell phones cause cancer of the brain or nervoussystem?

(a) P(x80)=enter your response here

(Round to four decimal places asneeded.)

(b) What does the result from part(a) suggest about the mediareports?
