Question #1
The paired data below consist of the temperatures on randomly
chosen days and the amount a certain kind of plant grew (in
millimeters). Test the claim that there is a linear correlation
between temperature and plant growth, with 0.01 significance level
and P-Value method.

Recorded here are the germination times (in days) for sixteen
randomly chosen seeds of a new type of bean: 11, 13, 12, 13, 20,
15, 18, 17, 14, 18, 10, 12, 13, 17, 14, 17 Send data to Excel
Assuming that germination times are normally distributed, find a
95% confidence interval for the mean germination time for all beans
of this type. Then complete the table below. Carry your
intermediate computations to at least three decimal places. Round

1. Over a period of 100 randomly chosen trading days in 1993, a
basket of small growth stocks returned an average of 13.37% while a
basket of diversified stocks returned an average of 19.63%. The
standard deviations were 20.39% and 12.85% respectively. On
average, did these two investment vehicles produce significantly
different returns? Test at the 0.05 level of significance

In a certain lottery, six numbers are randomly chosen form the
set {0, 1, 2, ..., 49} (without replacement). To win the lottery, a
player must guess correctly all six numbers but it is not necessary
to specify in which order the numbers are selected.
(a) What is the probability of winning the lottery with only one
ticket?
(b) Suppose in a given week, 6 million lottery tickets are sold.
Suppose further that each player is equally likely to choose...

6. Listed below are actual high temperatures and the high
temperatures that were forecast five days earlier. Use a .05
significance level to test the claim of a zero mean difference
between the actual high temperatures and the high temperatures that
were forecast one day earlier. Use our 4-step procedure. This is a
matched or paired samples hypothesis test. Actual high: 80 77 81 85
73 High forecast one day earlier: 78 75 81 85 76

In a certain lottery, an urn contains balls numbered 1 to 34. From this urn, 4 balls are chosen randomly, without replacement
In a certain lottery, an urn contains balls numbered 1 to 34.
From this urn, 4 balls are chosen randomly, without replacement.
For a $1 bet, a player chooses one set of four numbers. To win,
all four numbers must match those chosen from the urn. The order in
which the balls are selected does not matter. What is the
probability of winning this lottery with one ticket?
