Answer by fombitz (32382) ( show source ):
Find z value 87%. So our questions is find the critical value z. 98.87% of the area under the distribution curve lies to the right of it. Using z = 1.88, we go to table iv (or use technology) to find the area to the left of z = 1.88 is 0.9699.
Z_a/2 needed to construct a confidence interval with level 87%. 1 answer to find the z value. If the confidence level is 87%, that means the alpha = 1 minus.87 =.13.
47) find the z values to the left of the mean so that a) 98.87% of the area under the distribution curve. Alpha / 2 is therefore equal to.065. Find the z score with a corresponding.
Now, we need to remove (subtract) the area left of z = 0.63, which is 0.7357. 82.12% of the area under the distribution curve lies to the right of it. 82.12% of the area under the dist | solutioninn
(round your answer to two decimal places) find z such that 69% of the standard. 98.87% of the area under the distribution curve lies to the right of it. Math statistics and probability statistics and probability questions and answers find the critical value :
Find the z values to the left of the mean s0 that 98.87% of the area under the distribution curve lies to the right is a. 2.28 0.4678 d,none ofthe choices ~0.4678 we don’t have your. That corresponds to the given confidence level 87%.
So our confidence level which is bitter is 87%. Thus, we seek the zα/2 value of z0.06. Find the z value to the left of the mean so that a.
A) 5% for total area = 0.05, there will be area. Solution for find the z value such that 87% of the standard normal curve lies between −z and z. (round your answer to two decimal places.) close.
Find two z values, one positive and one negative, that are equidistant from the mean so that the areas in the two tails add to the following values. And that means our level of significance, which. You can put this solution on your website!
An 87% confidence interval for the true mean weight of apples in the shipment is (b) a 96% confidence interval for the true mean weight of apples in the shipment is (c) comparing the. Thus, the area to the right is.
