2. A medical researcher measured the pulse rates(beats per minute) of a sample of randomly selected adults found the following student’s t-based confidence interval:
With 95% Confidence, 70.887604<µ(Pulse)<74.497011
a. Explain carefully what the software output means.
b. What is the margin of error for this interval? (show me how to do it in TI-84)
c. If the researcher had calculated a 99% confidence interval, would the margin of error be larger or smaller? Explain.

The heights (in inches) and pulse rates (in beats per minute)
for a sample of
99
women were measured. Using technology with the paired
height/pulse data, the linear correlation coefficient is found to
be
0.6130.613.
Is there sufficient evidence to support the claim that there is
a linear correlation between the heights and pulse rates of women?
Use a significance level of
alpha?equals=0.050.05.

1.The sample mean is an unbiased estimator for
the population mean. This means:
The sample mean always equals the population mean.
The average sample mean, over all possible samples, equals the
population mean.
The sample mean will only vary a little from the population
mean.
The sample mean has a normal distribution.
2.Which of the following statements is
CORRECTabout the sampling distribution of the
sample mean:
The standard error of the sample mean will decrease as the
sample size increases....
