Answer:
A. There is not sufficient evidence to conclude that the mean price of a single-family home has decreased
Step-by-step explanation:
To study : Whether the mean price of single family home has decreased or not -
Null Hypothesis [H0] = There is no change in mean price of single family home
Alternate Hypothesis [H1] = There is change (decrease) in mean price of single family home
If the null hypothesis is not rejected, it implies that 'there is no change in mean price of single family home' has been statistically accepted.
So, it states that - There is not sufficient evidence to conclude that the mean price of a single-family home has decreased
Answer: the answer would be B :)
Answer:
x = -4
Step-by-step explanation:
3x + 3 +9 = box
3x = -12
3x/3 = -12/3
x = -4
Step-by-step explanation:
area = ( base 1 + base 2 ) ÷ 2 x height
50 = ( 10 + 15) ÷2 x height
50 ÷ 12.5 = height
height = 4
