In a regression analysis of a first-order model involving 3 predictor variables and 25 observations, the following estimated regression equation was developed.



= 10 - 18x1 + 3x2 + 14x3



also, the following standard errors and the sum of squares were obtained.



sb1 = 3 sb2 = 6 sb3 = 7
sst = 4800 sse = 1296


the p-value for testing the significance of the regression model is

a.
less than .01.

b.
between .025 and .05.

c.
between .01 and .025.

d.
greater than .10.

a. is not found to be significant.

Step-by-step explanation:

Regression analysis is a statistical technique which is used for forecasting. It determines the relationship between two variables. It determines the relationship of two or more dependent and independent variables. It is widely used in stats to find trend in the data. It helps to predict the values of dependent and independent variables. In the given question, there are 25 observations and the regression equation is given. X and Y are considered as dependent variables.

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
