Ling wants to determine the average distance she travels each day in her car. She records the odometer reading, which measures t

erica [24]

Answer:

$Mean = 10724.29\ mi$

Step-by-step explanation:

Given

$n = 7$ --- days

See attachment for odometer readings

Required

The mean of the distance

Mean is calculated as:

$Mean = \frac{\sum x}{n}$

So, we have:

$Mean = \frac{10150 + 10211 + 10424 + 10769 + 10884 + 11155 + 11477}{7}$

$Mean = \frac{75070}{7}$

$Mean = 10724.2857143$

Approximate

$Mean = 10724.29\ mi$

A perfume company claims that the mean weight of ther new perfume is at least 8.9 fluid oz. Express the null hypothesis and the

zlopas [31]

Answer:

$H0: mu = 8.9 fl oz.\\\\$

$Ha: mu ≠8.9 fluid oz$

Step-by-step explanation:

Given that A perfume company claims that the mean weight of ther new perfume is at least 8.9 fluid oz

For testing this claim, in Statistics we perform a certain measures called hypothesis testing.

For this first step is to create null and alternate hypothesis.

Normally null hypothesis would have some statistic = something

Here we want to test the mean weight of perfume

Hence null hypothesis would be

H0: mu = 8.9 fl oz.

Alternate hypothesis would be opposite of this claim

i.e.

Ha: mu ≠8.9 fluid oz

Hence answer is

$H0: mu = 8.9 fl oz.\\\\$

$Ha: mu ≠8.9 fluid oz$
