An experiment using 35 guinea pigs is set up to study the weight of the pigs after injecting them with a drug. if the population mean is 23.5 grams with a standard deviation of 3.4 grams, what is the margin of error of the sample mean?

1.1264

Step-by-step explanation:

Given : An experiment using 35 guinea pigs is set up to study the weight of the pigs after injecting them with a drug.

To Find: If the population mean is 23.5 grams with a standard deviation of 3.4 grams, what is the margin of error of the sample mean?

Solution:

n = 35

Confidence interval = 95%. So, z =1.96

Margin of error =

Margin of error =

Margin of error =

Hence the margin of error of the sample mean is 1.1264.

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

hope i

pretty sure 750 each month!
