Calculate the correlation coefficient. (Round to three
decimal places.)
r = 0.964
Let's test the significance of the correlation coefficient
at α =
0.01 significance level.
Ho There is not a significant relationship between the
year and high temperature, i.e., p = 0.
Ha There is a significant relationship between the year
and high temperature, i.e., p = 0.
a. Calculate the test statistic. Round to three decimal
places.
↓ =
b. Calculate the p-value. Round to four decimal places.
p-value
= 0.0000
c. Make a decision.
Ꮕ
Reject the null hypothesis.
Do not reject the null hypothesis.
d. Is there enough evidence to support that there is a
significant relationship between the year and high
temperature?
No
Yes
