1) Determine the probability of the treatment group’s mean being greater than the control group’s mean by 8 points or more. Then complete the statements. The significance level is set at 5%, and the probability of the result is 3.6%, which is less than the significance level. The result is not statistically significant

2)Which statement is true about the result considering a significance level of 5%?

A) The result is not statistically significant, which implies that this result could be due to random chance.
B) The result is not statistically significant, which implies that spraying the corn plants with the new type of fertilizer does increase the growth rate.
C) The result is statistically significant, which implies that spraying the corn plants with the new type of fertilizer does increase the growth rate.
D) The result is statistically significant, which implies that spraying the corn plants with the new type of fertilizer does not increase the growth rate.

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
