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>
Answer:
Overall percentage is 125% than you can - 15% which = 110%
10 % = 2700 as this is the profit. 2700 x 10 = 100% = Rs 270,000
Well dont you have to bring down the zeros than you will have the answer
Variable varies or changes
constatant term doesn't change
examples
variables can change so example
x>10
x can be 11 or 33 or anythign bigger than 10
constants are no fun
they don't change an are boring, like
3 or 8, it just stays that way
