Question

The standard deviation of pulse rates of adult males is more than 11 beats per minute. This is a claim about a population proportion so a normal distribution is assumed. The claim undergoes a hypothesis test using a significance level of α = 0.05. The P-value based on sample data is calculated to be 0.345.

State the null hypothesis (H0).
State the alternative hypothesis (H1).
What kind of test would this be, a two-tailed, a left-tailed, or a right-tailed?
Sketch a normal distribution curve and highlight the region of significance (also called critical region or rejection region).
On your graph, next highlight the P-value. (The P-value means that there is a 34.5% chance that your results could be random or happen by chance).
State a conclusion about the null hypothesis. (Reject H0 or fail to reject H0.)
Without using technical terms or symbols, state a final conclusion that addresses the original claim.

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.
