Answer:
REQUIRED TEST STATICS IS 35.19
Step-by-step explanation:
total size of sample = 10,000
men women
voted 2777 3466
did not vote 1444 2313
By chi square test we can find the relationship between gender and participation in the election
<em>
</em>
where
a represent = 2777, b = 3466, c= 1444, d = 2313, N = 10000
Putting values to get chis square statics
<em>
</em>
<em>
</em>

Answer:
$1200
Step-by-step explanation:
The clustering method for estimation is a method used for estimating the sums and products of numbers. This method is used when the numbers that are to be multiplied or added are near in value to a single number.
Given the money raised by six fund raisers:
$212, $205, $206, $190, $188, and $195
The numbers are to be added to find the total money raised. i.e.:
$212 + $205 + $206 + $190 + $188 + $195
But all the numbers are close to $200. Hence:
Using clustering method = $200 + $200 + $200 + $200 + $200 + $200 = 6 * $200 = $1200
