Step-by-step explanation:
-Given the two heights are similar:
#Heidi's flowered bed dimensions and volume is calculated as:
#The width of Andrew's is twice Heidi's. The width and volume is thus calculated as:
#Total soil volume of the soil used is determined by summing the two different flowerbed volumes:

Answer:
p-value: 1.000
There is enough evidence at the 1% level of significance to suggest that the proportions are not equal.
Step-by-step explanation:
We will be conducting a difference of 2 proportions hypothesis test
The hypothesis for this test is:
H_0: p1 - p2=0
H_a: p1 - p2 ≠0
(p1 ) = 252/300 = 0.84
(p2) = 195/300 = 0.65
This is a 2 tailed test with a significance level of 1%. So our critical values are: z > 2.575 and z < -2.575
