According to records, the amount of precipitation in a certain city on a November day has a mean of 0.10 inches, with a standard
Andru [333]

Answer:

The probability that the mean daily precipitation will be 0.11 inches or less for a random sample of November days

P(X≤ 0.11) = 0.4404

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that the mean of the Population = 0.10 inches

Given that the standard deviation of the population = 0.07inches

Let 'X' be a random variable in a normal distribution

Z = \frac{x-mean}{S.D} = \frac{0.11-0.10}{0.07} = 0.1428

<u><em>Step(ii):-</em></u>

The probability that the mean daily precipitation will be 0.11 inches or less for a random sample of November days

P(X≤ 0.11) = P(Z≤0.1428)

               =  1-P(Z≥0.1428)

              =  1 - ( 0.5 +A(0.1428)

            =  0.5 - A(0.1428)

            = 0.5 -0.0596

           = 0.4404

<u><em>Final answer:-</em></u>

The probability that the mean daily precipitation will be 0.11 inches or less for a random sample of November days

P(X≤ 0.11) = 0.4404

The time to fly between New York City and Chicago is uniformly distributed with a minimum of 120 minutes and a maximum of 150 mi
rewona [7]

Answer:

a. 8.66 minutes

Step-by-step explanation:

Since the flight times are uniformly distributed, the standard deviation can be calculated as follows:

\sigma = \frac{b-a}{\sqrt{12}}

Where '<em>b' </em>is the maximum flight time (150 minutes) and '<em>a' </em>is the minimum flight time (120 minutes):

\sigma = \frac{150-120}{\sqrt{12}}\\\sigma = 8.66\ minutes

The distribution's standard deviation is 8.66 minutes.
