Suppose that in a random selection of 100 colored candies, 29% of them are blue. The candy company claims that the percentage of blue candies is equal to 23%. Use a 0.05 significance level to test that claim. What is the test statistic
Homework Answers
Answer #1
We have for given example,
Population proportion value is =0.23
x=29
n=100
Estimate for sample proportion =0.29
Z test statistic formula for proportion
=1.426
| Z test statistic = 1.43 |
