Answer:
99% CI:

Step-by-step explanation:
We have to calculate a 99%CI for the difference of means for the vegan and the omnivore.
First, we have to estimate the standard deviation

The MSE can be calculated as

The weighted sample size nh can be calculated as

The standard deviation then becomes

The z-value for a 99% confidence interval is z=2.58.
The difference between means is

Then the confidence interval can be constructed as

Answer:

Step-by-step explanation:
Answer:8:30 PM (20:30) Previous Day
Step-by-step explanation:
Answer:
Triangle is isosceles triangle X = 9
Step-by-step explanation:

Since we are solving the quadratic equation because the highest degree in the equation is second. We arrange in the form of ax²+bx+c = 0.

Combine like terms.

Solve the equation by factoring.

Hence the values of x that make f(x) = g(x) are -3 and 1.
