Zara is conducting research on ring-tailed lemurs and collects the following data on the lengths of tails in cm for 11 full-grown females in a particular group. 62 59 57 60 61 58 63 56 57 57 60

Given that these lengths are normally distributed in the entire population, what is the width of the 95% confidence interval for the mean length? Give your answer as a single number rounded to three significant figures.

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
