Is not
Step-by-step explanation:
Given that population mean of IQ after 5 years for a child is 100.
A sample of 20 mothers in the first trimester of their pregnancy are asked to play Mozart in the house at least 30 minutes each day until they
give birth. This sample had a mean of 104.1 with std dev =15
Since population std dev is not known and sample size is small, we can use t test
(Right tailed test at 5% significance level)
Std error of sample mean =
Test statistic t = mean difference / std error
= 1.222
p value = 0.1187=0.119
Do not reject H0 becasue the P-value is not less than the a-0.05 level of significance
There (1)_____is not________sufficient evidence at the a=0.05 level of significance to conclude that mothers who listen to Mozart have children with higher IQs.
So if each person eats 1/3 pizzas. And he makes 4 pizzas. There are 3 1/3s in 1 pizza. 3*4 = 12.
The answer is 12 guests
