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:
Hip breadths less than or equal to 16.1 in. includes 90% of the males.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 14.5
Standard Deviation, σ = 1.2
We are given that the distribution of hip breadths is a bell shaped distribution that is a normal distribution.
Formula:

We have to find the value of x such that the probability is 0.10.
P(X > x)
Calculation the value from standard normal z table, we have,

Hence, hip breadth of 16.1 in. separates the smallest 90% from the largest 10%.
That is hip breaths greater than 16.1 in. lies in the larger 10%.
