emmainna [20.7K]

Answer:

z = \frac{981.7 -997}{\frac{62}{\sqrt{73}}}= -2.108

And we can use the normal standard distribution table or excel and with the complement ruler we got:

P(z>-2.108) =1- P(z

Step-by-step explanation:

We know the following info given:

\mu = 997 represent the true mean

\sigma = \sqrt{3844}= 62 represent the population deviation

n = 73 represent the sample size selected

Since the sample size is large enough (n>30) we can use the central limit theorem and the sample mean would have the following distribution:

\bar X \sim N (\mu, \frac{\sigma}{\sqrt{n}})

And for this case we want to find this probability:

P(\bar X >981.7)

And we can use the z score formula given by:

z= \frac{\bar X -\mu}{\frac{\sigma}{\sqrt{n}}}

And replacing we got:

z = \frac{981.7 -997}{\frac{62}{\sqrt{73}}}= -2.108

And we can use the normal standard distribution table or excel and with the complement ruler we got:

P(z>-2.108) =1- P(z

Is -8 rational or irrational
ANEK [815]

Answer:

olga_2 [115]

Answer:

P(X=3cars) = 0.052

P(X>3 cars) = 0.00638

Step-by-step explanation:

In total there are 7 cars per hour.

Using formulae for geometric Probability

P(X=3) = (7^3×e-7)/3! = 0.0521

P(X>3cars) = (7^2× e-7)/2! =

P(X>3) = 0.0128/2×1 =0.00638
