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
Answer:
A x-198,y-99
Step-by-step explanation:
since sin p/h you can say
perpendicular is 99
and hypotenuse is x
sin 30=99/x
x=198
and cos is b/h
base is y
and hypotenuse is x
cos 30=y/198
y-99
Answer:
See below
Step-by-step explanation:
625 = 25^2, or (5^2)^2 = 5^4
