RUDIKE [14]

Answer:

Carter's coins could be;

3 of 5¢, 2 of 10¢, 1 of 25¢, and 1 of 50¢

Step-by-step explanation:

The available coin denominations are;

1¢ = 1 penny, 5¢, 10¢, 25¢, 50¢, and $1.00

Since the coins are more than $0.95, we can have;

5¢ × 3

10¢× 2  

25¢× 1

50¢

Total = $1.00

That is his coins could have been 3 × 5¢, 2 × 10¢, 1 × 25¢, and 1 × 50¢, to make a total of 7 coins with an amount value of $1.00.

A prior study estimated as 34%. The analysts would like to conduct a second study on the same topic with a margin of error, E, o
Volgvan
The minimum sample size required for a test with a confidence interval of 100(1 - \alpha )% with a z-score of z_{ \alpha /2} and margin of error of E and a population proportion of p is given by:

n= \frac{p(1-p)z_{ \alpha /2}^2 \alpha }{E^2}

Given p = 34% = 0.34, E = 0.027, z_{ \alpha /2}=1.645

Therefore, 

n= \frac{0.34(1-0.34)(1.645)^2}{0.027^2}  \\  \\ = \frac{0.34(0.66)(2.706025)}{0.000729} = \frac{0.60723201}{0.000729}  \\  \\ =832.97=833
