At 0.01 significance level the hypothesis is rejected.
Null Hypothesis (H₀): The sample data occurs purely from chance.
Alternative Hypothesis (H₁): The sample data is influenced by some non-random cause.
If the p-value of the hypothesis test is less than some significance level (e.g. α = .01), then we can reject the null hypothesis and conclude that we have sufficient evidence to say that the alternative hypothesis is true.
Given that,
x = 28
s = 2.9
μ = 31
n = 8
α = 0.01
Then, the Null Hypothesis : H₀ = 31
The Alternate Hypothesis : H₁ < 31
The average number of cigeratte smoker per day is less than 31.
Test Statistics:
t = x -μ / s√n
= 28 - 31/ 2.9√8
= -3/ 8.41
= -0.356
Since the p-value of 0.0046 is less than the significance level of 0.01, the auditor rejects the null hypothesis.

Pretty sure the answer is c
The angle x is complimentary to the given angle
Therefore x = 90-29 = 61 degrees

Well, first, you would fine how much she put in the bank in the first place!
250,000-96,000=154,000
Then you would do 154,000*0.02 to find how much interest is charged per month.
154,000*0.02=3080
Finally, you would multiply 3080 by 6 {because you need to account for all of the months}.
3080*6=18,480

If you want to know her percentage, we do:
16 ÷ 25 = 0.64
0.64 × 100 = 64%
Her score is 64%
