I'm making some extreme memories with the last piece of this inquiry.

The lengths of pregnancies in a little country town are regularly appropriated with a mean of 261 days and a standard deviation of 16 days.

If you somehow happened to draw tests of size 59 from this populace, in what reach would you hope to track down the center 68% of most midpoints for the lengths of pregnancies in the example?

Between and ?

In the event that an examination decides the distinction in normal compensation of subpopulations of individuals with blue eyes and individuals with earthy colored eyes isn't critical, at that point the populaces if blue-peered toward individuals and earthy colored looked at individuals are _______ various pay rates.

The Ministry of Agriculture in its battle against the military worm disease of maize

ranches in the nation has endorsed three brands of synthetics A, B and C to be utilized

by ranchers as follows: Farmers are to consolidate precisely two of the synthetic compounds to splash

their ranches or they should utilize none of them. The extents of ranchers who selected

for synthetics A, B and C are separately given by 1 , 1 and 7 . A rancher is arbitrarily 53 15

chosen from the gathering of ranchers. What is the likelihood that the rancher picked

none of the synthetic compounds?

I have an inquiry on my measurement/likelihood schoolwork. These are the issues. Any assistance would be extraordinarily refreshing!

The measure of time to finish an actual work in a PE class is around regularly ordinarily circulated with a mean of 34.9 seconds and a standard deviation of 6.9 seconds.

a) What is the likelihood that an arbitrarily picked understudy finishes the action in under 27.9 seconds? Round to 3 decimal spots. Inaccurate

\\8\\

b) What is the likelihood that a haphazardly picked understudy finishes the action in more than 39.5 seconds? Round to 3 decimal spots.

c) What extent of understudies take somewhere in the range of 28.7 and 38.8 seconds to finish the movement? Round to 3 decimal spots.

d) 70% of all understudies finish the action in under seconds. Round to 1 decimal spot.
