Answer:
Since Her goal is to earn $ 300 , but now she is earning only $270 ,Hence Celia will not achieve her goal .
Step-by-step explanation:
Given as :
The cost of each calendar = $ 9
The number of calendar sold to the family = 16
The number of calendar sold to the neighborhood = 14
So, Total number of calendar sold by Celia = The number of calendar sold to the family + The number of calendar sold to the neighborhood
i.e Total number of calendar sold by Celia = 16 + 14 = 30
∵ The cost of each calendar = $ 9
∴ The cost of 30 calendar = $ 9 × 30 = $ 270
Since Her goal is to earn $ 300 , but now she is earning only $270 ,Hence Celia will not achieve her goal . Answer

So, the probability is 1/6
Answer:
Option D) significantly different from 24
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 24
Sample mean,
= 25
Sample size, n = 16
Alpha, α = 0.05
Population standard deviation, σ = 2
First, we design the null and the alternate hypothesis
We use Two-tailed z test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Since,
The calculated z statistic does not lie in the acceptance region, we fail to accept the null hypothesis and reject it. We accept the alternate hypothesis.
Thus, it can be concluded that the mean age is
Option D) significantly different from 24
