Question

Assume a significance level of alpha equals 0.1 and use the given information to complete parts (a) and (b) below.

Original claim: The standard deviation of pulse rates of a certain group of adult males is more than 17 bpm. The hypothesis test results in a P-value of 0.2678

a. State a conclusion about the null hypothesis. (Reject Upper H 0 or fail to reject Upper H 0.) Choose the correct answer below.

A. Reject Upper H 0 because the P-value is less than or equal
to **a**

B.Reject Upper H 0 because the P-value is greater than
**a**

C.Fail to reject Upper H 0 because the P-value is less than or
equal to **a**

D.Fail to reject Upper H 0 because the P-value is greater than
**a**

b. Without using technical terms, state a final conclusion that addresses the original claim. Which of the following is the correct conclusion?

A.There is sufficient evidence to support the claim that the standard deviation of pulse rates of the group of adult males is more than 17 bpm.

B.The standard deviation of pulse rates of the group of adult males is less than or equal to 17 bpm.

C.The standard deviation of pulse rates of the group of adult males is more than 17 bpm.

D. There is not sufficient evidence to support the claim that the standard deviation of pulse rates of the group of adult males is more than 17 bpm.

information to complete parts (a) and (b) below.
Original claim: Women have heights with a mean equal to 156cm.
The hypothesis test results in a P-value of 0.0676
a. State a conclusion about the null hypothesis. (Reject H0 or
fail to reject H0.) Choose the correct answer below.

Claim: The standard deviation of pulse rates of adult males is
less than 11 bpm. For a random sample of 144 adult males, the pulse
rates have a standard deviation of 9.6 bpm. Find the value of the
statistic.

Claim: the standard deviation of pulse rates of adult males is more
than 12 bpm. For a random sample of 127 adult males, the pulse
rates have a standard deviation is 13.2 bpm. Find the value of the
test statistic.

Claim: Fewer than 96% of adults have a cell phone. In a
reputable poll of 1196 adults, 86% said that they have a cell
phone. Find the value of the test statistic. The value of the test
statistic is. (Round to two decimal places as needed.)
Claim: The mean pulse rate (in beats per minute) of adult
males is equal to 69 bpm. For a random sample of 138 adult males,
the mean pulse rate is 69.9 bpm and the...

Use the pulse rates in beats per minute (bpm) of a random sample
of adult females listed in the data set available below to test the

Claim: The standard deviation of pulse rates of adult males
is
less thanless than 11 bpm. For a random sample of 158 adult
males, the pulse rates have a standard deviation of 10.6 bpm.
Complete parts (a) and (b) below.
a> Express the original claim in symbolic form.
2. identify the null and the alternative hypotheses.

h1=

In a recent poll, 801 adults were asked to identify their
favorite seat when they fly, and 476 of them chose a window seat.
Use a 0.05 significance level to test the claim that the majority
of adults prefer window seats when they fly. Identify the null
hypothesis, alternative hypothesis, test statistic, P-value,
conclusion about the null hypothesis, and final conclusion that
addresses the original claim. Use the P-value method and the
normal distribution as an approximation to the binomial...
