Apublisher reports that 37% of their readers own a laptop. a marketing executive wants to test the claim that the percentage is actually different from the reported percentage. a random sample of 350 found that 30% of the readers owned a laptop. find the value of the test statistic. round your answer to two decimal places.

p(s)  = - 2.71

Step-by-step explanation:

Test of proportion

sample size       n  =  350

Publisher report             37 %      0,37

Sample proportion          30 %      0.30

p(s)  = [ ( p  -  p₀ ) /√(p₀q₀/n ]      ⇒  p(s)  = - 0.07*(18.70)/√(0.37)*(0.63)

p(s)  = - 1.3095/0.4828

p(s)  = - 2.71
