Answer:
of cream will remain in the container.
Step-by-step explanation:
Given:
Amount of cream in the container =
Amount of cream used to make crème brûlée =
We need to find the amount of cream remain in the container.
Solution:
Now we can say that;
the amount of cream remain in the container is equal to Amount of cream in the container minus Amount of cream used to make crème brûlée.
framing in equation form we get;
amount of cream remain in the container =
Now we will make the denominator common using LCM we get;
amount of cream remain in the container =
Now denominators are common so we will solve the numerators.
amount of cream remain in the container =
Hence of cream will remain in the container.
Answer:
And we can find the p value using the following excel code:
"=1-CHISQ.DIST(20.5,11,TRUE)"
Step-by-step explanation:
A chi-square goodness of fit test "determines if a sample data matches a population".
A chi-square test for independence "compares two variables in a contingency table to see if they are related. In a more general sense, it tests to see whether distributions of categorical variables differ from each another".
We need to conduct a chi square test in order to check the following hypothesis:
H0: Each month is equally likely to be the birth month for any given individual
H1: Each month is NOT equally likely to be the birth month for any given individual
The statistic to check the hypothesis is given by:
After calculate the statistic we got
Now we can calculate the degrees of freedom for the statistic given by:
And we have categories =12 since we have 12 months in a year
And we can calculate the p value given by:
And we can find the p value using the following excel code:
"=1-CHISQ.DIST(20.5,11,TRUE)"
