Question
You wish to test the following claim (Ha) at a significance level of =0.01=0.01. Ho:p=0.4:=0.4 Ha:p>0.4:>0.4 You obtain a sample of size n=693=693 in which
You wish to test the following claim (Ha) at a significance level of =0.01=0.01. Ho:p=0.4:=0.4 Ha:p>0.4:>0.4 You obtain a sample of size n=693=693 in which there are 300 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 Ho is true) the probability of observing...
- at most 300 successful observations
- at least 300 successful observations
What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value =
The p-value is...
- less than (or equal to)
- greater than
This test statistic leads to a decision to...
- reject the null
- accept the null
- fail to reject the null
As such, the final conclusion is that...
- There is sufficient evidence to warrant rejection of the claim that the population proportion is greater than 0.4.
- There is not sufficient evidence to warrant rejection of the claim that the population proportion is greater than 0.4.
- The sample data support the claim that the population proportion is greater than 0.4.
- There is not sufficient sample evidence to support the claim that the population proportion is greater than 0.4.
