According to the last census (2010), the mean number of people per household in the United States is LaTeX: \mu = 2.58 Assume a

Veseljchak [2.6K]

Answer:

P(2.50 < Xbar < 2.66) = 0.046

Step-by-step explanation:

We are given that Population Mean, $\mu$ = 2.58 and Standard deviation, $\sigma$ = 0.75

Also, a random sample (n) of 110 households is taken.

Let Xbar = sample mean household size

The z score probability distribution for sample mean is give by;

Z = $\frac{Xbar-\mu}{\frac{\sigma}{\sqrt{n} } }$ ~ N(0,1)

So, probability that the sample mean household size is between 2.50 and 2.66 people = P(2.50 < Xbar < 2.66)

P(2.50 < Xbar < 2.66) = P(Xbar < 2.66) - P(Xbar $\leq$ 2.50)

P(Xbar < 2.66) = P( $\frac{Xbar-\mu}{\frac{\sigma}{\sqrt{n} } }$ < $\frac{2.66-2.78}{\frac{0.75}{\sqrt{110} } }$ ) = P(Z < -1.68) = 1 - P(Z 1.68)

= 1 - 0.95352 = 0.04648

P(Xbar $\leq$ 2.50) = P( $\frac{Xbar-\mu}{\frac{\sigma}{\sqrt{n} } }$ $\leq$ $\frac{2.50-2.78}{\frac{0.75}{\sqrt{110} } }$ ) = P(Z $\leq$ -3.92) = 1 - P(Z < 3.92)

= 1 - 0.99996 = 0.00004

Therefore, P(2.50 < Xbar < 2.66) = 0.04648 - 0.00004 = 0.046

zhannawk [14.2K]

Answer:

Total sales revenue use excel function : ( SUMIF. =sumif(range, criteria, [sum_range] )

For each of the stores: Use excel function: For Store 1: =sumif(B4:B99,1,I4:I99) then repeat same for Store 2 to store 8

Step-by-step explanation:

To modify the spreadsheet to calculate the total sales revenue we will add a column " sales revenue "

multiply values of column : ( unit sold * unit price ) to get Total sales revenue. then use excel function : ( SUMIF. =sumif(range, criteria, [sum_range] ) to find Total sales revenue

calculate the total revenue for each of the 8 stores using a pivot table using "store identification number" in row and " sales revenue " in values field

To get the sales revenue ; replace " store identification value" with sales region " column
