(a+b)^2 – (a-b)^2

Since both are squares you end up with

(a+b +a-b) * (a+b –(a-b))

 

First set of parenthesis add the 2 a’s together to get 2a and subtract b from b

<span> So you end you with 2a</span>

<span> Now you have</span>

2a(a+b –(a-b))

Second set of parenthesis you subtract a from a and then have b+b left which equals 2b

<span> So now you have 2a times 2b</span>

<span> Which equals 4ab</span>

Assume that the annual household expenditure on sugar is approximately normally distributed with a mean of $8.22 and a standard
irina1246 [14]

 To solve this problem, we will have to make use of the z statistic. The formula for the z score is given as:

z = (x – u) / s

where,

x is the sample value = more than $10.00

u is the sample mean = $8.22

s is the standard deviation = $1.10

 

Substituting the values into the equation to solve for z:

<span>z = (10 – 8.22)  / 1.10</span>

z = 1.78 / 1.10

z = 1.62

 

We then look for the p value using the standard distribution tables at the specified z score value = 1.62. Since this is a right tailed test, therefore the p value is:

p = 0.0526

or

p = 5.26%

 

<span>Therefore there is a 5.26% probability that a household spent more than $10.00</span>
