A simple random sample of 50 items from a population with 7 resulted in a sample mean of 35.
Vilka [71]

The 90% , 99% confidence interval for the population mean is 32.145 < \rm \mu < 35.855 and 31.093 <  \rm \mu < 36.907

<h3>What is Probability ?</h3>

Probability is the study of likeliness of an event to happen.

It is given that

Total Population = 50

Mean = 35

The confidence interval is given by

\rm CI = \mu + z \dfrac{s}{\sqrt n}

\rm \mu is the mean

z is the confidence level value

s is the standard deviation

n is the population width

(a) The 90% confidence interval for the population mean

90% \rm \alpha / 2  = 0.05

Z = 1.64

34 \rm \pm 1.64 * 8 / √50

34 \rm \pm  1.855

32.145 < \rm \mu < 35.855

(b)  The 99% confidence interval for the population mean

99% \rm \alpha / 2  = 0.005

Z=2.57

34  \rm \pm 2.57 * 8 / √50

34 \rm \pm  2.907

31.093 <  \rm \mu < 36.907

Therefore the confidence interval for population mean has been determined.

The complete question is

A simple random sample of 50 items from a population width =7  resulted in a sample mean of 35. If required, round your answers to two decimal places.

a. Provide a 90% confidence interval for the population mean

b. Provide a 99% confidence interval for the population mean

Does the tallest can always hold the greatest volume? Explain your answer!
djverab [1.8K]

Alrighty, so,  you know how young children often believe that a taller container will have a greater volume than a shorter container? Even after seeing that both containers hold the same amount, some children will still think the taller container holds more. It may take measuring the water a few times before they get it.

<em>If it overflows, the first container is bigger, or is able to hold more water. If all of the water from the first container can be poured into the second container without completely filling it, then the second container holds more water.</em>

The tallest container holds the most liquid. Identical containers can have a different capacity.
