Svetach [21]

There are 900 calories in 180 crackers. Write 60 calories for 12 crackers as 60/12. Then make x/180, showing that there are 180 crackers with an unknown amount of calories. Cross multiply 60 and 180, which is 10,800. Divide 10,800 by 12, and you get 900.

You intend to estimate a population proportion with a confidence interval. The data suggests that the normal distribution is a r

SIZIF [17.4K]

Answer:

The critical value that corresponds to a confidence level of 99% is, 2.58.

Step-by-step explanation:

Consider a random variable <em>X</em> that follows a Binomial distribution with parameters, sample size <em>n </em>and probability of success <em>p</em>.

It is provided that the distribution of proportion of random variable <em>X, </em> $\hat p$ , can be approximated by the Normal distribution.

The mean of the distribution of proportion is, $\mu_{\hat p}=\hat p$

The standard deviation of the distribution of proportion is, $\sigma_{\hat p}=\sqrt{\frac{\hat p(1-\hat p)}{n}}$ .

Then the confidence interval for the population proportion <em>p</em> is:

$CI=\hat p\pm z_{\alpha /2}\sqrt{\frac{\hat p(1-\hat p)}{n} }$

The confidence level is 99%.

The significance level is:

$\alpha =1-\frac{Confidence\ level}{100}=1-\frac{99}{100}=1-0.99=0.01$

Compute the critical value as follows:

$z_{\alpha /2}=z_{0.01/2}=z_{0.005}$

That is:

$P(Z>z)=0.005\\P(Z$

Use the <em>z</em>-table for the <em>z-</em>value.

For <em>z</em> = 2.58 the P (Z < z) = 0.995.

And for <em>z</em> = -2.58 the P (Z > z) = 0.005.

Thus, the critical value is, 2.58.

Inessa05 [86]

Answer:

10.846 hours

Step-by-step explanation:

first you add all the calories= 1410 calories

then you divide 1410 calories by 130 (the calories you can burn in one hour)

your answer is 10.846 which means that it takes 10.846 hours to consume 1410 calories.
