An epidemiologist is worried about the prevalence of the flu in East Vancouver and the potential shortage of vaccines for the area. She will need to provide a recommendation for how to allocate the vaccines appropriately across the city. She takes a simple random sample of 334 people living in East Vancouver and finds that 43 have recently had the flu. Suppose that the epidemiologist wants to re-estimate the population proportion and wishes for her 95% confidence interval to have a margin of error no larger than 0.03. How large a sample should she take to achieve this?

The length of the base of a right-angled triangle ABC is 6 centimeters and the length of the hypotenuse is 10 centimeters. Find the area of the triangle.

Answers

Answer:

Step-by-step explanation:

Ok, so we see that we have 6 as a leg of the right triangle and 10 as the hypotenuse. As we look closer, we can tell that this makes the Pythagorean triple 6, 8, 10. 6, 8, 10 is just the Pythagorean triple 3, 4, 5 but it is multiplied by 2. So now that we know both the legs of this right triangle, we can use the area of a triangle formula (bh)/2. 6*8=48 and 48/2 = 24 which gives us our answer.

Weston completed a hypothesis test and found that he could not reject the null hypothesis. Which of the following is a valid reason for his conclusion? A.The z-statistic is less than 0.
B.The z-statistic lies in the critical region.
C.The z-statistic is greater than 0.
D.The z-statistic lies outside the critical region.

Answers

Answer: D.The z-statistic lies outside the critical region.

Step-by-step explanation:

When we run a hypothesis test , the result of that test will be a probability value. The probability value is represented by a “p value” .

It tells us if hypothesis statement is probably true or not.

If the value falls in the rejection region, it means you have statistically significant results; You can reject the null hypothesis.

If the p-value falls outside the rejection region, it means your results aren’t enough to throw out the null hypothesis.

Hence, if Weston ound that he could not reject the null hypothesis. The z-statistic lies outside the critical region would be the valid reason for his conclusion.

The right answer for the question that is being asked and shown above is that: "D.The z-statistic lies outside the critical region." Weston completed a hypothesis test and found that he could not reject the null hypothesis. A valid reason for his conclusion is that D.The z-statistic lies outside the critical region.

Which of the following is equivalent tothe expression below?
(5x +6y- 3z) (3x- 8y+ z)
A. 8x- 14y- 4z
B. 8x- 2y -2z
C. 8x- 14y- 2z
D.8x -2y -3z

Answers

I believe the answer is B.
5+3=8
therefore being 8x
6-8=-2
therefore being -2y
-3+1=-2
there for being -2z
8x-2y-2z

hope this helps
