Answer:
We can be 95% confident that consumers spend between $4.04 and $15.96 less at Store A than the consumers spend at Store B.
Step-by-step explanation:
Confidence Intervals give an estimate as range of values for a statistic concerned at a <em>confidence level</em>.
In this case the statistic is the mean difference between Store A and Store B purchase amounts and the confidence level is 95%.
Confidence Interval can be calculated using M±ME where
- M is the sample mean difference between Store A and Store B purchase amounts
- ME is the margin of error from the mean
Answer:
62%
Step-by-step explanation:
31/50 is also equal to 62/100 (if we multiply the numerator and denominator by 2). 62/100 is 62%.
Answer: 113.04 cm³
Step-by-step explanation: To find the volume of a sphere, start with the formula for the volume of a sphere which is shown below.

Here, we are given that our sphere has a radius of 3 centimeters.
So plugging into the formula, we have
.
Start by simplifying the exponent.
(3 cm)³ is equal to 3 centimeters · 3 centimeters ·
3 centimeters or 27 cm³.
So we have
.
Notice that we can cross-cancel 3 and 27 to 1 and 9.
So we have (4)(9 cm³) which is equal to 36 cm³.
So we have 36π cm³.
So the volume of the sphere is 36π cm³.
Remember that π is approximately equal to 22/7 or 3.14 so we can estimate the value of the volume by plugging in 3.14 for π.
So we have (36)(3.14) which is equal to 113.04 which means
that the volume of approximately equal to 113.04 cm³.
