Answer:
Point Estimate for different between population means = - 0.99
Step-by-step explanation:
We are given data of two samples and we have to find the best point estimate of the true difference between two population means. Remember that in absence of data about population the best estimator is the sample data. So, we will find the means of both sample data and find the difference of that means. This difference between the means of sample data will be the best point estimate for the true difference between the population means.
Formula to calculate the mean is:
Mean of Sample 1:
Mean of Sample 2:
Therefore the best point estimate for difference between two population means would be = Mean of Sample 1 - Mean of Sample 2
= 128.55 - 129.54
= - 0.99
Answer:
Step-by-step explanation:
we know that
The volume of the triangular prism is equal to
where
B is the area of the triangular base
L is the length of the triangular prism (also is called the height of the prism) is the perpendicular distance between the triangular bases
we have
substitute
Answer:
Remember that 6x^2 and -4x are not like terms. I drew a circle around them since those two will come first then goes the 5 and 3. Hopw this helps, thank you !!
