In a survey of 500 voters, 430 said they would vote for the same candidate again. what percent of the voters would vote the same way again?

86%

Step-by-step explanation:

To find the percent, divide the number who say they would vote the same, 430, by the total number of voters.

430/500 = 0.86

The decimal is converted to a percent by multiplying the decimal by 100.

0.86*100 = 86%

it is probably the graph on the bottom right.

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
