Answer:
Step-by-step explanation:
Data given and notation
represent the sampe size for A
represent the sample size for B
represent the sample deviation for A
represent the sample deviation for B
represent the significance level provided
F test is a statistical test that uses a F Statistic to compare two population variances, with the sample deviations s1 and s2. The F statistic is always positive number since the variance it's always higher than 0. The statistic is given by:
Solution to the problem
System of hypothesis
We want to test if we have the same variation, so the system of hypothesis are:
H0: 
H1: 
Calculate the statistic
Now we can calculate the statistic like this:
Answer:
-3/2/5
Step-by-step explanation:
8p + 2 > -15 - 2
5p > -17
P > - 17/5
P > - 3/2/5
Answer:
1.36
Step-by-step explanation:
if 2 yards are 6 feet then divide 8.16 by 6. and you get your unit price which is 1.36
Answer:
Y equals 1/2 x -4 and passes through the point 6 / -2
Step-by-step explanation:
Answer:
Algebraic grouping symbols parentheses, brackets, braces, radicals, and fraction lines show where a group starts and ends, and help to establish the order used to apply math operations. Terms inside a grouping symbol have to be operated upon before they can be acted upon by anything outside the grouping symbol.
