Question
You wish to test the following claim (Ha) at a significance level of a = 0.05.
H.:p = 0.65
H,:p > 0.65
You obtain a sample of size n = 189 in which there are 131 successful observations. For this test,
you should use the (cumulative) binomial distribution to obtain an exact p-value. (Do not use the
normal distribution as an approximation for the binomial distribution.)
The p-value for this test is (assuming H, is true) the probability of observing...
O at most 131 successful observations
O at least 131 successful observations
What is the p-value for this sample? (Report answer accurate to four decimal places.)
p-value =
The p-value is..
O less than (or equal to) a
O greater thana
This test statistic leads to a decision to...
O reject the null
O accept the null
O fail to reject the null
As such, the final conclusion is that...
O There is sufficient evidence to warrant rejection of the claim that the population proportion is
greater than 0,65.
O There is not sufficient evidence to warrant rejection of the claim that the population
proportion is greater than 0.65.
O The sample data support the claim that the population proportion is greater than 0.65.
O There is not sufficient sample evidence to support the claim that the population proportion is
greater than 0,65.
