x greater than negative 2, because ln(x) is undefined for x <= 0 (-2+2=0, -1.999...+2>0)
Answer:
The policy has an effect because the null hypothesis rejected since P-value < significance level.
Step-by-step explanation:
Since (P-value = 0.0108) < 0.1 significance level, we have sufficient evidence to show that the mean is not equal to 39.8. This means that the policy has an effect on the average number of the emails received per day.

Answer:
2. it is the y intercept. they are parallel but intercept y at different points
3. the all have different growth rates but same y intercept. that is why they are increasing at different rates but all intersect.
4. legit just change the y intercept
5. ok and change the slope in the same way you would have changed the y in the last problem
By multiplying the round with the decimal number and you get the nearest degree
