Answer:
The number of ways is 26,400 ways
Step-by-step explanation:
Given;
total number of men, M = 10
total number of women, W = 12
number of committees to be formed = 6
If there must be equal gender, then it must consist of 3 men and 3 women.
Therefore, the number of ways is 26,400 ways
Answer:
The p value can be calculated from the alternative hypothesis with this probability:
And the best option for this case would be:
C. between 0.01 and 0.05.
Step-by-step explanation:
Information provided
represent the number of smokers from the sample in 1995
represent the number of smokers from the sample in 2010
sample from 1995
sample from 2010
represent the proportion of smokers from the sample in 1995
represent the proportion of smokers from the sample in 2010
represent the pooled estimate of p
z would represent the statistic
represent the value for the pvalue
System of hypothesis
We want to test the equality of the proportion of smokers and the system of hypothesis are:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Where
Replacing the info given we got:
The p value can be calculated from the alternative hypothesis with this probability:
And the best option for this case would be:
C. between 0.01 and 0.05.
