Answer:
a: no the sample size is too small
b: Yes, the distribution is normal with a mean of 40 and standard deviation of 12
Step-by-step explanation:
a: If n < 30, we need to know that the sample is normally distributed or else we can't determine anything. When sample sized get very large, they usually resemble normally distributed data sets so we can still make conjectures even if the data isn't officially normally distributed
b: The question tells us that the sample is normally distributed, so even though n < 30, we can still make conjectures about the population
5 over and 4 ^. not sure if this is correct but that’s what i got
We must find the perimeter of all eight windows. To make it simpler for us, let's find the perimeter of one window and multiply it by 8.
2*3.5 + 2*5 = 7 + 10 = 17
17*8 = 136
Hope this helps!
