P-value approach and determine critical value

Reference no: EM13102154

A fast food chain wants to determine whether there are differences between three media (magazine, TV or radio) in terms of consumer recall of an ad. The result are

remembering the ad magazine = 25 tv= 10 radio = 7 and tv = 42
not remembering the ad magazine = 73 tv = 93 radio = 108 and tv = 274

Is this problem a ChiSq problem using the test for independence?

I am to compute expected values, test stat, use p-value approach and determine critical value with alph at .05
