Answer: 0.1788
Step-by-step explanation:
We assume that the monthly rent for a one-bedroom apartment without a doorman in Manhattan is normally distribution.
Given : Mean monthly rent :
Standard deviation :
Sample size :
Let x be the monthly rent of randomly selected apartment.
Now. we calculate the value of z-score by the formula :
For x = $2,700
The p-value =
Hence, the probability that the average rent of the sample is more than $ 2,700 = 0.1788
Answer:
Correct Answer is B.) 4.8 units
$570.60 because 90/100=.90 so multiply that with 634 with .90 you get 570.60
Answer:
a number produced from a subset of the group of interest.
Step-by-step explanation:
This problems is, basically, about the difference of concepts between a statistic and a parameter.
When something is taken from a sample and estimated to the entire population, it is a statistic. For example, if you survey 200 Central New York residents, an 60% of them say they are Buffalo Bills fans, the 60% is a statistic.
When something is true to the entire population, it is a parameter. If i study the voting preference of all 53 players on the Buffalo Bills active roster, and 83% are Democrats, the 83% is an parameter.
So the correct answer is:
a number produced from a subset of the group of interest.
This subset is the sample, for example, and the group of interest is the population.
