(15.04) 10.4 Hypoth esis Testing for Population oportions KASEY COR esson 10.4 -Hypothesis Testing for Population Proportions 1 of 1 PROBLEM A sample of 1100 computer chips revealed that 60% or he chips do not ful n the isn000 hours of her ist ne co patys prone and lineature clamed that 58% do not fal in the first 1000 bors of ther use. Use a oos level of signifiance. Find the vale of he test sta se Round your answer to 2 decimal places TESTSTATISTIC Enter the value of the test statistic Round your answer to 2 decimal places) 0

Explanation / Answer

Standard Error, se = sqrt(P*(1-P)/n), where P is the hypothesized value 0.58

se = sqrt(0.58*0.42/1100) = 0.014881

Test statistic, Z = (p-P)/se = (0.60-0.58)/0.014881 = 1.34
