Answer:
3
Step-by-step explanation:
We have given , and SP =30
We have to find the slope for regression on Y from X
The slope on Y from X is given by
As we have given the value of SP =30 and value of
So slope for regression will be
Answer:
A. T > 2.539
Step-by-step explanation:
We have a hypothesis test of the mean, with unknown population standard deviation.
The hypothesis are:
From the hypothesis we can see that the test is right-tailed, so the critical value of t should be a positive value.
The degrees of freedom can be calculated as:
The significance level is 0.01, so the critical value tc should be the one that satisfies:
Looking up in a t-table, for 19 degrees of freedom, this critical value is tc=2.539.
