you have to multiply the 5 and the 7 and you get 35 then subtract 98 and 35 and you get 63
The answer is 6.6 because it’s the only number between 6.5 and 6.7 so 6.6 is your answer
Answer:

Step-by-step explanation:
Answer:
1) Reject null hypothesis if t > 3.143
2) t = 2.008
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 8
Correlation, r = 0.634
Significance level = 0.01
First we design the null and the alternate hypothesis:
This is a one tailed test.
1) Decision rule
Degree of freedom = n - 2 = 6
So if the calculated test statistic is greater than 3.143, we fail to accept the null hypothesis and reject it.
2) Test statistic
