A survey of 131 investment managers in Barron's Big Money poll revealed the following:
• 43% of managers classified themselves as bullish or very bullish on the stock market.
• The average expected return over the next 12 months for equities was 11.2%.
• 21% selected health care as the sector most likely to lead the market in the next 12 months.
• When asked to estimate how long it would take for technology and telecom stocks to resume sustainable growth, the managers' average response was 2.5 years.
a. Cite two descriptive statistics.
b. Make an inference about the population of all investment managers concerning the average return expected on equities over the next 12 months.
c. Make an inference about the length of time it will take for technology and telecom stocks to resume sustainable growth.
Compute the test statistic. At 95% confidence using the p-value approach, test to see if taking the course actually increased scores on the driving exam.
Why is the F distribution important? How do you determine if a significant difference exists among the groups in ANOVA? How do you determine differences between the groups in ANOVA?
For planning purposes, the hospital physician staff would like to know the probability that a given patient is a smoker if the patient has serious illness.
Determine the conditions under which you would use a discrete probability distribution rather than a continuous probability distribution. Provide one (1) example to illustrate your reasoning.

In the week before and the week after a holiday, there were 10,000 total deaths, and 4972 of them occurred in the week before the holiday.
A sample of 20 is taken, resulting in a mean of 16.45 and standard deviation of 3.59. Assume that x is normally distributed and used alpha of 0.5 to test hypotheses.
How are the goals of the tests similar and different? How are the tests used? What are the purposes of giving these differing tests?
