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.
Just multiply and the answer should be in=78x
Answer:
The answer is B.
Step-by-step explanation:
The question asks us to select an explanatory variable and a response variable which are just different names for independent and dependent variables.
Explanatory or independent variables, as the name suggests, are not affected by any other variable in the equation.
Response or dependent variables change according to the changes in other variables in the equation.
Out of the four options given in the question, the option b should be chosen according to the requirements because diameter of the apple affects its weight but the diameter itself is independent of the weight variable.
The plot should show that the weight changes according to the diameter variable.
I hope this answer helps.
