Random samples of size 17 are taken from a population that has 200 elements, a mean of 36, and a standard deviation of 8. Which of the following best describes the form of the sampling distribution of the sample mean for this situation? a. Approximately normal because the sample size is small relative to the population size b. Approximately normal because of the central limit theorem c. Exactly normal d. None of these alternatives is correct.
Answers
None of the given alternatives described the Sample mean for the situation. A complete solution is below.
Given values are:
Sample size,
- n = 17
Mean,
- μ = 36
Standard deviation,
- σ = 8
As we know,
The Standard deviation of sample mean,
→
By substituting the values, we get
→
→
→
Thus the response i.e., "option d" is appropriate.

The Westwood Warriors basketball team wants to score more points. To get better at scoring points the team is trying to improve its offensive strategies. Some opponents primarily use a zone defense, while others primarily use a man-to-man defense. When the Warriors play against teams that use a zone defense they score an average of 67 points per game with a standard deviation of 8 points per game. When they used a new offensive strategy against this defense, they scored 77 points. What is the Z-score of this value

Step-by-step explanation:
Given the number: 0.035 which has three decimal place
- Case 1: if we multiply by 10
=> we have: 0.035*10 = 0.35
Hence, the product 0.35 which is smaller than 1 (we do not accept)
- Case 2: if we multiply by 1000
=> we have: 0.035*1000 = 35
Hence, the product 35 which is greater than 1 and less than 100
- Case 3: if we multiply by 100
=> we have: 0.035*100= 3.5
Hence, the product 3.5 which is greater than 1 and less than 100
- Case 4: if we multiply by 10000
=> we have: 0.035*10000= 350
Hence, the product 350 which is greater than 100 (we do not accept)
Therefore, we have two expression:

Answer:
-1113
Step-by-step explanation:
You apparently want the sum of the 14-term arithmetic sequence ...
-21, -30, -39, ..., -138
The average term is ...
(-21 -138)/2 = -79.5
so the sum of the 14 terms is ...
(14)(-79.5) = -1113
17
Σ (15 – 9n) = -1113
η = 4
- nth term
aₙ = 15 - 9n
a₄ = 15-9*4 = 15-36= -21
a₁₇ = 15 - 9(17) = -138
- Sum;
S = (a₁ + aₙ)*n/2
n = 14
a₁ = a₄= -21
aₙ = a₁₇ = -138
S = (-21 - 138)*14/2
S = -1113
