In a test of Ho: μ = 50 against H₂: μ> 50, the sample data yielded the test statistic z = 2.11. Find and interpret the p-value for the test.Click the icon to view a table of standard normal valuesThe p-value is p =(Round to three decimal places as needed.)Interpret the results. What does this p-value mean?OA. The probability of observing a z-value < 2.11 is equal to the p-value, if µμ = 50.OB. The probability of observing a z-value > 2.11 is equal to the p-value, if μ>50.OC. The probability of observing a z-value > 2.11 is equal to the p-value, if μ = 50.O D. The probability of observing a z-value < 2.11 is equal to the p-value, if μ > 50.

The null and alternative hypothesis isH0:Ha:Test statistic(z)=2.11

Chpt 4, Q1: what is the correct answer?
The probability of area of standard normal curve between z = 0.63 and the mean is? %3D Select one: O a. 73.5% O b. 23.5% O c. 98.7% O d. 42.3% O e. 35.5%
This assignment is worth 1 points. The extra point will be added to your overall course grade. For example: if you receive an 88% in the course you can receive up to 1 point giving you a new score of 89%. The following rubric will be used. 0.25 point for drawing the normal distribution curve with the mean value labeled on the curve and the appropriate area shaded. 0.25 point for determining the value of the standard deviation of the sample mean. 0.5 point for finding the correct probability. All work must be shown in order to receive any credit. Please upload your completed assignment here. The length of time taken on the SAT for a group of students is normally distributed with a mean of 2.5 hours and a standard deviation of 0.25 hours. A sample size of n = 60 is drawn randomly from the population. Find the probability that the sample mean is between two hours and three hours.
In a particular statistics exam, the 35th percentile of final exam score is 42, and the 70th percentile of final exam score is 76. A histogram of the scores approximately follows the normal curve. What is the approximate standard deviation of the final exam scores? Hints: What is the z value in the normal table that gives you closest to 35% of the area between -z and z? Now what does that tell you about the number of SDs in between 42 inches and 76 inches? You might find it helpful to draw a picture of the normal curve with original units and standard units. Group of answer choices a. 7.5 b. 13.1 c. 20.7 d. 37.8

Gentle Ben is a Morgan horse at a Colorado dude ranch. Over the past 8 weeks, a veterinarian took the following glucose readings from this horse (in mg/100 ml). 95 86 80 103 99 110 82 87 The sample mean is x = 92.8. Let x be a random variable representing glucose readings taken from Gentle Ben. We may assume that x has a normal distribution, and we know from past experience that o = 12.5. The mean glucose level for horses should be u = 85 mg/100 ml.t Do these data indicate that Gentle Ben has an overall average glucose level higher than 85? Use a = 0.05. (a) What is the level of significance? State the null and alternate hypotheses. Will you use a left-tailed, right-tailed, or two-tailed test? O Ho: H = 85; H,: µ + 85; two-tailed O Ho: H = 85; H,: µ > 85; right-tailed O Ho: H = 85; H,: u 85; H,: u = 85; right-tailed (b) What sampling distribution will you use?
