Answer:
40%
Step-by-step explanation:
12 divided by 30 will give you 0.4
Answer:
d. 0.0948 ± 4.032(0.0279)
Step-by-step explanation:
A 99% confidence interval for the coefficient of promotional expenditures is, First, compute the t critical value then find confidence interval.
The t critical value for the 99% confidence interval is,
The sample size is small and two-tailed test. Look in the column headed es = 0.01 and the row headed in the t distribution table by using degree of freedom is here
for (n-2=5) degree of freedom and 99% confidence ; critical t =4.032
therefore 99% confidence interval for the slope =estimated slope -/+ t*Std error
= 0.094781123 -/+ 4.032* 0.027926367 = -0.017822 to 0.207384
First find the slope(m)
Slope= y2-y1/x2-x1= (1-(-5))/(-1-(-2))= 6/1 = 6
Then find the y intercept (move up six and right one from (-1, 1) to get (0, 7)
The y-intercept is y=7
Now make the equation
Y= slope(x) + y-intercept
Y=6x+7
It would be 13 meters, took the same test and it was the answer lol
good luck if you haven't
already taken it!!<span />
