Answer:
The probability is 1.
Explanation:
Despite that the he distribution is positively skewed, the distribution of sample means of one-bedroom apartments will still be a a normal distribution based on Central Limit Theorem.
Since we have
μ = mean = 2200
SD = standard deviation = 250
n = sample size = 50
Therefore,
Standard error = SD ÷ √n
= 250 ÷ √50
= 250 ÷ 7.07106781186548
= 35.3553390593274 approximately 35.36
Standardize xbar to z = (xbar - μ) ÷ (SD ÷ √n)
Therefore, we have:
P(xbar > 1,950) = P(z > (1,950 - 2200) ÷ 35.36)
= P(z > - 250 ÷ 35.36)
= P(z > -7.07) = 1
Therefore, the probability of selecting a sample of 50 one bedroom apartments is 1 which can be said to be certain.
Answer:
Option "2" is the correct answer to the following statement.
Explanation:
A short-term loan is a form of loan received to endorse short term business and personal wealth for a very short period. It is a tempting and temporary option, for most of the short term businesses which are not easily eligible for a loan from a financial institution.
