Answer:
Step-by-step explanation:
12 men and 18 women: x1; 14 days; y1
8 men and 16 women: x2; ?; y2
12/18 simplified is equal to 2/3
8/16 simplified is equal to 1/2
This is a direct proportion, thus we can say that:
(1/2*14)/(2/3)=y2
7/(2/3)=10.5 days
I hope this helped you get out of homework trouble :D
OwO
Answer:
Because it increases the risk of Type 1 error
Step-by-step explanation:
ANOVA is the analysis of the variance .
When comparing more than two treatment means we use ANOVA because a t test increases the risk of type 1 error .
For example if we wish to compare 4 population means there will be 4C2 = 6 separate pairs and to test the null hypothesis that all four population means are equal would require six two sample t test. Similarly to test 10 population mean would require 45 separate two sample t test.
This has two disadvantages .
First the procedure is too lengthy and tediuos.
Second the overall level of significance greatly increases as the number of t- tests increases.
The analysis of the variance compares two different estimates of variance using the F distributionto determine whether the population means are equal.
Answer:
the mean is 5

Are you in middle school ( specifically 6th grade) bc i think i had that like a week ago lol...
Step-by-step explanation:
A "deduction" is used to determine a conclusion to prove a principle. Essentially look at and study points that are given with logic, conditions, and rules. You compare how the area compares with the rules and therefore no deduction is wrong.
Therefore, the answer is A.
Best of Luck!
