Suppose that in a random selection of 100 colored candies, 20% of them are blue. The candy company claims that the percentage of blue candies is equal to 23%. Use a 0.01 significance level to test that claim.
Identify the null and alternative hypotheses for this test.
Identify the number of events, the number of trials, the claimed population proportion, and the significance level to be used in technology.
Identify the test statistic for this hypothesis test.
Identify the P-value for this hypothesis test.
Here claim is that p=0.23
As null hypothesis always have equality sign, so hypothesis here is vs
Claimed population proportion is p=0.23 and
As n is sufficient large test statistics is
P value is
As P value is greater than alpha we fail to reject the null hypothesis
Hence we have sufficient evidence to support the claim that p=0.23
