Answer:
Step-by-step explanation:
From the given information;
The null and alternative hypothesis is:


sample mean x = -2
population mean = 0
SD = 6
sample size n = 25
Using t-test statistics:


t = -1.667
P-value = P(t ≤ -1.667) + P(t ≥ 1.667)
P-value = 0.1086
Since P-value is greater than
, we fail to reject

Anna has more money... We don't have to do messy calculations for this... Both have 10 to the 2nd power "some amount". 10 to the second power is 100. So they both have 100 coins.
A quarter is 25 cents, while a dime is only 10 cents. Since they both have the same amounts of coins, the one with 100 quarters has more money, so Anna has more money than Jasmine.
Now, we need to figure put by how much! 100 quarters is one hundred 25 cent coins. 100*25 = 2500. That is 25 dollars. Whereas, Jasmine has one hundred times 10 cents, which is 1000 cents. This is 10 dollars.
So, Anna has 15 more dollars than Jasmine.
