The average number of passes in a football game is right skewed with mean 75 and variance 961. If we sample 100 random games, wh
suter [353]

Answer:

0.0066

Step-by-step explanation:

Given that:

Mean \mu = 75

Variance \sigma^2 =961

The standard deviation \sigma =  \sqrt{961} = 31

The sample size n = 100

\mu = \mu_{\overline x} = 75

\sigma _{\overline x} = \dfrac{\sigma }{\sqrt{n}}

\sigma _{\overline x} = \dfrac{31 }{\sqrt{100}}

\sigma _{\overline x} = \dfrac{31 }{10}}

\sigma _{\overline x} = 3.1

P(\overline x > 83.7) = 1 - P( \overline x < 83.7)

P(\overline x > 83.7) = 1 -P\bigg (  \dfrac{\overline x - \mu_{\overline x} }{\sigma _{\overline x}} < \dfrac{83.7 - 76}{3.1} \bigg)

P(\overline x > 83.7) = 1 -P\bigg (  Z< \dfrac{7.7}{3.1} \bigg)

P(\overline x > 83.7) = 1 -P (  Z< 2.48)

Using the Z table;

P(x > 83.7) = 1 - 0.9934

P(x > 83.7) = 0.0066

Thus, probability = 0.0066

Fynjy0 [20]

Answer: 1,000

First, you have to find how much 7.5% is coming out of 10,000. So in this case it's 750. Multiply 750 by 12 years. Thats 9000, you then subtract 9000 and 10,000 to get 1,000.
