Answer:

$.56

Step-by-step explanation:

The first minute is .50 cents and the subtotal was 5.60. Subtract for the first minute to get the subtotal for 9 minutes.

(5.60-.50=5.10)

5.10 is the amount for 9 minutes so now we will divide to get the price for each minute.

(5.10÷9=.56)

This means each minute after the first minute is $.56 cents.

Answer:

95%

Step-by-step explanation:

For a given sample data, the width of the confidence interval would vary directly with the confidence level i.e. more the confidence level, wider will be the confidence interval.

This is because the critical value associated with the confidence level(e.g z value) becomes larger as the confidence level is increased which results in an increased interval.

The confidence interval for a population proportion is given by the formula:

$p \pm z\sqrt{\frac{pq}{n} }$

So, for a fixed value of p,q and n, the larger the value of z the wider will be the confidence interval.

Hence 95% confidence interval will be wider than 80% confidence interval.
