Answer: Approximately 43.3%

Work Shown:

13+15+2 = 30 games total

Divide the number of games won (13) over the number total (30)

13/30 = 0.433 approximately which converts to 43.3% of the games won

To convert from decimal form to percent form, move the decimal point over to the right two spaces. Another example would be 0.83 converts to 83%

Answer:

43%

Step-by-step explanation:

First, find the total amount of games:

13 + 15 + 2

= 30

Then, to find the percentage of games won, divide 13 by 30:

13/30

= 0.43

So, the team won approximately 43% of its games

Answer:

The 95% confidence interval $81.852 < \mu < 280.098$

Step-by-step explanation:

From the question we are told that

The sample mean is $\= x = 180.975$

The standard deviation is $\sigma = 143.042$

The sample size is n = 8

Given that the confidence level is 95% then the level of significance is

$\alpha =( 100- 95) \%$

=> $\alpha =0.05$

Generally from the normal distribution table the critical value of $\frac{\alpha }{2}$ is

$Z_{\frac{\alpha }{2} } = 1.96$

Generally the margin of error is mathematically represented as

$E = Z_{\frac{\alpha }{2} } * \frac{\sigma }{\sqrt{n} }$

=> $E = 1.96 * \frac{ 143.042 }{\sqrt{8} }$

=> $E = 99.123$

Generally 95% confidence interval is mathematically represented as

$\= x -E < \mu < \=x +E$

=> $180.975 -99.123 < p < 180.975 +99.123$

=> $81.852 < \mu < 280.098$

➷ Find the multiplier:

1 + (3.4/100) = 1.034

Use this formula:

Final = original x multiplier^n

n is the number of years

Substitute the values in:

final = 6000 x 1.034^3

Solve:

final = 6633.0438

This can be rounded to the final answer of £6633.04
