A film distribution manager calculates that 9%9% of the films released are flops. If the manager is right, what is the probabili

alexdok [17]

Answer:

The probability that the proportion of flops in a sample of 442 released films would differ from the population proportion by greater than 4% is:

= 0.094

= 9.4%

Step-by-step Explanation:

Estimated probability that the films released are flops = 9%

Sample of released films = 442

Estimated number of flops = 39.78 (442 * 9%)

If the population proportion of flops will be greater by 4%,

Therefore, the number of flops will increase to 41.37 (39.78 * 1.04)

This gives a new proportion of flops as 0.0936 (41.37/442)

The mean height of an adult giraffe is 17 feet. Suppose that the distribution is normally distributed with standard deviation 0.

BARSIC [14]

Answer:

Median =17

Step-by-step explanation:

Given that the mean height of an adult giraffe is 17 feet. Suppose that the distribution is normally distributed with standard deviation 0.9 feet.

Let X be the height of a randomly selected adult giraffe.

X is a random variable.

a) X is N(17, 0.9)

b) Median giraffe height = 17 ft since in normal distribution mean = median

c) When x = 18.5, Z = $\frac{18.5-17}{0.9} =0.1667$

d) $P(X$

e) $P(16.9$

f) 75th percentile for z is 0.675

$x=17.9+0.9(0.675)\\= 18.5075$
