Answer:

D. We are 95% confident that between about 22% and 28% of ESPN Viewers thought the Eagles would still win the division.

Step-by-step explanation:

We have to calculate a 95% confidence interval for the population proportion. The population is made up of ESPN viewers.

The sample proportion is p=0.25.

The standard error of the proportion is:

$\sigma_p=\sqrt{\dfrac{p(1-p)}{n}}=\sqrt{\dfrac{0.25*0.75}{914}}\\\\\\ \sigma_p=\sqrt{0.00021}=0.014$

The critical z-value for a 95% confidence interval is z=1.96.

The margin of error (MOE) can be calculated as:

$MOE=z\cdot \sigma_p=1.96 \cdot 0.014=0.028$

Then, the lower and upper bounds of the confidence interval are:

$LL=p-z \cdot \sigma_p = 0.25-0.028=0.222\\\\UL=p+z \cdot \sigma_p = 0.25+0.028=0.278$

The 95% confidence interval for the proportion of ESPN viewers is (0.222, 0.278) or (22.2%, 27.8%).

Based on the data in this two-way table, if a flower is picked at random, what is the probability of getting a yellow flower? Ty

garik1379 [7]

If what I'm reading is correct, there are, in total, 135 yellow flowers. Since the sample space is only the color of flowers, we do not need any additional information except the total amount of flowers there are, as this is the amount that we are taking the yellow flowers from. The total amount of flowers is 315. To find our answer, divide the amount of yellow flowers by the total amount of flowers:

135 divided by 315 = 0.49

Therefore, your answer would be 0.49

Hope this helps!
