Its the last one! Also if you dont know what I mean by this is, its the 4th one. You Welcome Merry Christmas
Answer: One sample z test for means
Step-by-step explanation:
From the information given, the sample size is large. It is greater than 30. Again, the population standard deviation is given. This means that the test statistic would be the z score which is determined by the formula
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = population standard deviation
The probability value would be determined from the normal distribution table.
Therefore, the hypothesis test that should be used is
One sample z test for means
The second one. Hope this helps:)

Answer:
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
The first term = 1500
2nd term = 900
3rd term = 540
The series is a GP.
r = 900/1500 = 0.6
The sum of the first 10 term, S₁₀, is as calculated below.
Sn = a(1-rⁿ)/(1-r)
S₁₀ = 1500(1 - 0.6¹⁰)/(1 - 0.6)
= 1500 × 0.9939/0.4
= 3,727.125 m
