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.

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
