360÷4=90
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.
$1495 ÷ 1.15 (that's 115%)
= $1300
there's your wholesale price.
we can check it to make sure it's correct:
$1300 × 1.15 = $1495
