A simple random sample of 32 men from a normally distributed population results in a standard deviation of 12.9 beats per minute
krok68 [10]

Answer:

Null Hypothesis, H0 = The pulse rates of men have a standard deviation equal to 10 beats per minute

Alternate Hypothesis, H1 = The pulse rates of men do not have a standard deviation equal to 10 beats per minute

Step-by-step explanation:

The null hypothesis is basically the problem statement i.e

Pulse rates of men have a standard deviation equal to 10 beats per minute

Hence, H0 = The pulse rates of men have a standard deviation equal to 10 beats per minute

The alternate hypothesis will contradict or negate the null hypothesis i.e

H1 = The pulse rates of men do not have a standard deviation equal to 10 beats per minute

A New York Times/CBS poll surveyed 1,027 adults nationwide about race relations in the United States. Of the sample, 61% respond
Naddik [55]

The interpretation is that we are 95% confident that the true population proportion p is somewhere between 0.58 and 0.64

The population proportion p in this case refers to the proportion of people who feel that race relations in this country are generally bad.

Something like 0.58 converts to 58% when you move the decimal point 2 spots to the right.
