Answer:
0.0021
Step-by-step explanation:
Given:
Probability of ordering a nonalcoholic beverage is, 
Number of samples are 
Now, the complement of event 'N' is not ordering a nonalcoholic beverage.
Therefore, 
Now, for a sample of '10' customers, the probability of not ordering a non alcoholic beverage is product of their individual probabilities as all these events are independent events.
Therefore, probability that none of the 10 will order a nonalcoholic beverage is given as:
![=[P(\overline N)]^{10}\\\\=(0.54)^{10}\\\\=0.0021](https://tex.z-dn.net/?f=%3D%5BP%28%5Coverline%20N%29%5D%5E%7B10%7D%5C%5C%5C%5C%3D%280.54%29%5E%7B10%7D%5C%5C%5C%5C%3D0.0021)

Answer:
The confidence interval for the difference in proportions is

No. As the 95% CI include both negative and positive values, no proportion is significantly different from the other to conclude there is a difference between them.
Step-by-step explanation:
We have to construct a confidence interval for the difference of proportions.
The difference in the sample proportions is:

The estimated standard error is:

The z-value for a 95% confidence interval is z=1.96.
Then, the lower and upper bounds are:

The confidence interval for the difference in proportions is

<em>Can it be concluded that there is a difference in the proportion of drivers who wear a seat belt at all times based on age group?</em>
No. It can not be concluded that there is a difference in the proportion of drivers who wear a seat belt at all times based on age group, as the confidence interval include both positive and negative values.
This means that we are not confident that the actual difference of proportions is positive or negative. No proportion is significantly different from the other to conclude there is a difference.
