Express the confidence interval 0.111 < p < 0.777  in the form ^ p± Ep ^±E.

And we know that this interval is calculated from this formula:

Where E represent the margin of error given by:

And we can calculate the sampel proportion with this operation:

And the error can be calculated as:

And the confidence interval would be given by:

Step-by-step explanation:

For this case we have the following interval given:

And we know that this interval is calculated from this formula:

Where E represent the margin of error given by:

And we can calculate the sampel proportion with this operation:

And the error can be calculated as:

And the confidence interval would be given by:

if you need just tell me and i will come to the rescue.

step-by-step explanation:

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;
