Births are approximately Uniformly distributed between the 52 weeks of the year. They can be said to follow a Uniform distribution from 1 to 53 (a spread of 52 weeks). Round answers to 4 decimal places when possible a. The mean of this distribution is born at the exact moment that week 36 begins is Px 36) between weeks 8 and 45 is P(8 < ®?45)- The probability that a person will be born after week 16 is P(x > b. The standard deviation is c. The probability that a person will be d. The probability that a person will be born h. Find the minimum for the lower f. P(x>201 x 46). Find the 48th percentile quartile.

(a) The mean of the distribution of births between the 52 weeks of a year is 27.

(b) The standard deviation of the distribution of births between the 52 weeks of a year is 15.01.

(c) The probability that a person is born exactly at the beginning of week 36 is 0.0192.

(d) The probability that a person will be born between weeks 8 and 45 is 0.7115.

(e) The probability that a person is born after week 16 is 0.7115.

Step-by-step explanation:

The random variable X can be defined as the births between the 52 weeks of the year.

The random variable X is uniformly distributed with parameters a = 1 to b = 53.

The probability distribution function of X is:

(a)

Compute the mean of the Uniformly distributed random  variable X as follows:

Thus, the mean of the distribution of births between the 52 weeks of a year is 27.

(b)

Compute the standard deviation of the  Uniformly distributed random  variable X as follows:

Thus, the standard deviation of the distribution of births between the 52 weeks of a year is 15.01.

(c)

Compute the probability that a person is born exactly at the beginning of week 36 as follows:

Use continuity correction.

P (X = 36) = P (36 - 0.5 < X < 36 + 0.5)

                = P (35.5 < X < 36.5)

Thus, the probability that a person is born exactly at the beginning of week 36 is 0.0192.

(d)

Compute the probability that a person will be born between weeks 8 and 45 as follows:

Thus, the probability that a person will be born between weeks 8 and 45 is 0.7115.

(e)

Compute the probability that a person is born after week 16 as follows:

Thus, the probability that a person is born after week 16 is 0.7115.

answer: 15

step-by-step explanation:

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.
