Question

mules have 63 chromosomes, while horses have 64 and donkeys have 62. while in colorado; describing threatened population of mules, Joshua described that the distribution of mule weights are normally distributed with a mean of 558.91 lbs. and a standard deviation of 56.99 lbs. sketch the normal probability density function. 41 percent of mule weights are more than _____ lbs?

Answer 1

X:Weights of mules as per Joshua(in Lbs)

X~N(=558.91,=56.99)

To find x so that

P(X>x) =0.41

=1-P(Xx) =0. 41

=1-P[(X-558.91/56.99)(x-558.91/56.99))

=1-P(Z(x-558.91)/56.99)

=1-(x-558.91/56.99)

Now,

1-0.41=(x-558.91/56.99)

InvNorm(0.41,0,1)=-0.2275

(x-558.91/56.99)=-0.2275

x=558.91-(0.2275*56.99)=545.9448

Ans) 41 percent of mule weights are more than ___545.9448__ lbs
