Answer:

Probability of choosing a Diamond= 9/26

Choosing a card that is not a club is=19/26

Step-by-step explanation:

These are the answers because...

Step one Add up all of the rows. 5+9+7+5=26
Step two, To find the probability of diamonds we need to take the total number of all the rows which is 26. And the number of diamonds which is 9. Then put it into a fraction 9/26
Step three to find the probability of choosing a card that is not a club, we would have to add up all the rows except the clubs which is 19, then out it over the total number which is 26. So 19/26
Hope this helped Please comment below on how you think my answer is. I would appreciate it Brainly

Answer:

The probability that the sample proportion will differ from the population proportion by greater than 0.03 is 0.009.

Step-by-step explanation:

According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.

The mean of this sampling distribution of sample proportion is:

$\mu_{\hat p}=p$

The standard deviation of this sampling distribution of sample proportion is:

$\sigma_{\hat p}=\sqrt{\frac{p(1-p)}{n}}$

As the sample size is large, i.e. <em>n</em> = 492 > 30, the central limit theorem can be used to approximate the sampling distribution of sample proportion by the normal distribution.

The mean and standard deviation of the sampling distribution of sample proportion are:

$\mu_{\hat p}=p=0.07\\\\\sigma_{\hat p}=\sqrt{\frac{p(1-p)}{n}}=\sqrt{\frac{0.07(1-0.07)}{492}}=0.012$
