Researchers are conducting a study in an attempt to establish a linear relationship between the number of online music video views and the number of guitar sales. A computer output for regression is shown and is based on a sample of seven observations. Predictor Coeff St. Dev t Ratio p-Value
Constant 7.85671094 1.316226455 5.969118 0.001889
Music Video Views 0.094781123 0.027926367 3.393965 0.019378

What represents the 99% confidence interval for the slope of the regression line?

Step-by-step explanation:

For this case we have the following output:

Predictor  Coeff            St. Dev           t Ratio      p-Value

Constant  7.85671094 1.316226455 5.969118 0.001889

Music Video Views 0.094781123 0.027926367 3.393965 0.019378

For this case the slope of the regression we have:

We assume that the standard error is:

The confidence interval would be given by:

The degrees of freedom are given by:

And the critical value using a significance level of is:

And replacing we got;

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90

there still no table
