Answer #1

Suppose we are sampling from a normally distributed population,
and we wish to use the t procedure to find a confidence interval
for the population mean. Consider the following 3 statements:
I. All else being equal, the greater the sample size, the
smaller the margin of error.
II. All else being equal, the greater the confidence level, the
greater the margin of error.
III. All else being equal, the greater the sample variance, the
smaller the margin of error.

1) A random sample of 10 observations was drawn from a large
normally distributed population. The data is below.
23,19, 24,17, 19, 23, 22, 22, 17, 16,
Test to determine if we can infer at the 8% significance level
that the population mean is not equal to 20, filling in the
requested information below.
A. The value of the standardized test statistic:
Note: For the next part, your answer should use
interval notation. An answer of the form (−∞,?) is
expressed...

BridgeRock is a major manufacturer of tires in the U.S.. The
company had five manufacturing facilities where tires were made and
another 20 facilities for various components and materials used in
tires. Each manufacturing facility produced 10,000 tires every
hour. Quality had always been emphasized at BridgeRock, but lately
quality was a bigger issue because of recent fatal accidents
involving tires made by other manufacturers due to tread
separation. All tire manufacturers were under pressure to ensure
problems did not...

A researcher is concerned that his new antihypertensive
medication may be causing insomnia in some of his patients. Suppose
he gathers a SRS of 65 patients treated with the study drug with a
sample average of 6.6 hours of sleep and a σ=1.1. Assuming that
insomnia can be quantified as an average of 4.5 hours of sleep, can
we determine with 95% confidence that his drug avoids diagnosis of
insomnia as a side-effect?
Ho: µ=4.5, Ha: µ<4.5
Z stat=12.4...
