The lengths of pregnancies in a small rural village are normally distributed with a mean of 261 days and a standard deviation of
valina [46]

Answer:

(221.39, 300.61) and (255.2223, 266.7777)

Step-by-step explanation:

Given that X, the  lengths of pregnancies in a small rural village are normally distributed with a mean of 261 days and a standard deviation of 17 days

Middle 98% would lie on either side of the mean with probability ±2.33 in the std normal distribution on either side of 0

Corresponding we have x scores as

Between 261-2.33*17 and 261+2.33*17

i.e. in the interval = (221.39, 300.61)

If sample size = 47, then std error of sample would be

\frac{17}{\sqrt{47} }

So 98% of pregnancies would lie between

261-2.33*\frac{17}{\sqrt{47} } and 262+2.33*\frac{17}{\sqrt{47} }

= (255.2223, 266.7777)

Deon drove 16 miles which is one fourth of the way home what’s the total length of the drive
svetlana [45]
64 miles

If 16 is 1/4 of the total distance, then x (the total distance) will be 4/4. To get 1/4 to equal 4/4, you multiply it by 4. Therefore you can multiply 16 by 4 to get 64 as the answer.
