Luda [366]

Answer:

82.5% Americans owned a TV also owned a DVD player .

Step-by-step explanation:

Formula

Percentage = \frac{Part\ value\times 100}{Total\ value}

As given

Of the 114.2 million Americans who owned a TV, 94.2 million also owned a DVD player.

Here

Part value = 94.2 million

Total value = 114.2 million

Putting all the values in the formula

Percentage = \frac{94.2\times 100}{114.2}

Percentage = \frac{94200\times 10}{1142\times 10}

Percentage = \frac{942000}{11420}

Percentage = 82.5 %

Therefore 82.5% Americans owned a TV also owned a DVD player .

Suppose the number of free throws in a basketball game by one player are normally distributed with a standard deviation 0.97 fre
babunello [35]

Answer: 1.960

Step-by-step explanation:

The value of z we use to calculate a confidence interval with a (1-\alpha) confidence level is a two-tailed test value i.e. represented by :-

              z_{\alpha/2}

Given : The level of confidence: 1-\alpha=0.95

Then, significance level : \alpha: 1-0.95=0.05

With the help of standard normal distribution table for z , we have

z_{\alpha/2}=z_{0.05/2}=z_{0.025}=1.960

Hence, the value of z should be used to calculate a confidence interval with a 95% confidence level =1.960

kap26 [50]

Answer:

10 hours

Step-by-step explanation:

If I have $50 in my bank account, and I want to have a total of $130 in my account. It means that I need to work enough hours to make $130 - $50 = $80.

If I make $8 per hour, and I need to make $80, then I just have to work 10 hours. ($80/8 = 10)
