Apublisher reports that 42% 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 170 found that 35% of the readers owned a laptop. find the value of the test statistic. round your answer to two decimal places.

The value of the test statistic to 2 decimal place is 1.91

Step-by-step explanation:

P cap= 0.42

n= 170

P= 0.35

q= 1-p

q= 1-0.35=0.65

Z=( pcap - p)/√(p*q)/n

Z= (0.42 - 0.35)/ √ (0.35*0.65)/170

Z= 0.07/√1.3383 * 10 ^ -3

Z= 1.91

Therefore the test statistic is z=1.91
