Step-by-step explanation:
When Deucalion threw one stone over his shoulder, 8 people appear. So, for every stone, we have 8 new people.
Therefore, if Deucalion threw 68 stones, the number of people that would appear is
Instead, when Phyrra threw a stone, 9 people appear. So, for every stone, we have 9 new people.
Therefore, if Phyrra threw 68 stones, the number of people that would appear is
And so, we can now calculate the total number of people that appear after each had thrown 68 stones:
Answer:
From the given data, there is not enough evidence to prove that there is a statistically significant difference between the two population means
Step-by-step explanation:
The number of younger moms, in the study = 837
The average weight gain of younger moms, ₁ = 30.67 pounds
The standard deviation of the weight gain of younger moms, s₁ = 14.69 pounds
(30.67 - 28.52)/√((14.69^2)/837 + 13²/143))
The number of younger moms, in the study = 143
The average weight gain of mature moms, ₂ = 28.52 pounds
The standard deviation of the weight gain of mature moms, s₂ = 13 pounds
The test statistic for the difference in two populations is given as follows;
Therefore, we get;
The test statistic ≈ (1.7919)
Using a graphing calculator, we get;
The critical-t = ±1.971379, p = 0.07459697
Therefore, given that the test statistic, (1.7919), < critical-t (0.07459697), we fail to reject the null hypothesis, therefor, the given data does not provide convincing evidence that there is a significant difference between the two population means
