Answer:
If we compare the p value and using any significance level for example always so we can conclude that we have enough evidence to reject the null hypothesis, and we can conclude that at 5% of significance the proportion for women made is higher than the proportion for male.
Step-by-step explanation:
Data given and notation
sample 1 male selected
sample 2 female selected
represent the proportion of male selected
represent the proportion of female selected
z would represent the statistic (variable of interest)
represent the value for the test (variable of interest)
Concepts and formulas to use
We need to conduct a hypothesis in order to check if the proportion for female is greater than males , the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
We need to apply a z test to compare proportions, and the statistic is given by:
(1)
Where
Calculate the statistic
Replacing in formula (1) the values obtained we got this:
Statistical decision
Since is a one sided test the p value would be:
If we compare the p value and using any significance level for example always so we can conclude that we have enough evidence to reject the null hypothesis, and we can conclude that at 5% of significance the proportion for women made is higher than the proportion for male.
The picture in the attached figure
we know that
if m ∠DAB=23.5°
then
arc DB=23.5°------> by central angle
the answer isarc DB=23.5°
1 worker earns 8/hour for 40 hrs.8 times 40=320 dollars in amount for 1st worker.the 2nd worker has the same 8 hrs for 40 hours therefore the same amounts.320+320=640
as a percentage:640 divided by 2000=0.32
0.32 times 100
=32 percent for both workers.16 percent for only 1 worker<span />
