Question

You wish to test the following at a significance level of α=0.01.

H0:p=0.83
H1:p<0.83

You obtain a sample of size n=623 in which there are 499 successful observations.

For this test, we use the normal distribution as an approximation for the binomial distribution.

For this sample...

The test statistic (z
) for the data = (Please show your answer to three decimal places.)
The p-value for the sample = (Please show your answer to four decimal places.)
The p-value is...
- less than (or equal to) α
greater than α
(Recall that when p(-value) is low, the null must go; when p(-value) is high, the null must fly)
Base on this, we should ....
- fail to reject the null hypothesis
- reject the null hypothesis
- accept the null hypothesis
As such, the final conclusion is that...
- The sample data suggest that the population proportion is significantly less than 0.83 at the significant level of α
= 0.01.
The sample data suggest that the population proportion is not significantly less than 0.83 at the significant level of α

= 0.01

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
