Answer:
At the end of the week Danielle is left with $99.91 in her account
Explanation:
The amount of money left in Danielle's account can be expressed as follows;
Amount left in Danielle's account=Initial Account balance+Earnings-Expenses
where;
Amount Left in Danielle's account=x
Initial Account balance=$127.02
And the earnings are as follows;
Garage sale=121.58
Birthday check=75
Total earnings=Birthday check+Garage sale=(75+121.58)=196.58
And the expenses are as follow;
Night out=66.14
Charitable donation=42.25
Doctor's appointment=115.30
Total expenditure=Night out+Charitable donation+Doctor's appointment=(66.14+42.25+115.30)=223.69
Replacing;
Amount left in Danielle's Account=127.02+196.58-223.69=99.91
At the end of the week Danielle is left with $99.91 in her account

Answer:
We'll start by putting into consideration, the large sample variance at the numerator.
Barron's Variance will be represented using 1 as the subscript.
i.e.
1 = $583 million
2 = $489 million
So,
0: 1²= 2²
: 1² ≠ 2²
=1² / 2²=
= $583 million² / $489 million²
= 583²/489²
= 1.42
Degrees of freedom 15 and 9
Using F table, area in tail is greater than 0.10.
Two-tail p-value is greater than .20
Exact p-value corresponding to F= 1.42 is .5874 (See F table)
p-value > .10
So,we do not reject 0.
We cannot conclude there is a statistically significant difference between the variances for the two companies.
