Listed below are systolic blood pressure measurements (mm Hg) taken from the right and left arms of the same woman. Assume that the paired sample data is a simple random sample and that the differences have a distribution that is approximately normal. Use a 0.05 significance level to test for a difference between the measurements from the two arms. What can be concluded? Right arm Left arm 148 174 OA. Ho Hd=0 H₁ Hd #0 135 121 137 134 D 170 190 152 134 In this example, He is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the measurement from the right arm minus the measurement from the left arm. What are the null and alternative hypotheses for the hypothesis test? OC. Ho Hd #0 H₁ Hd=0 Identify the test statistic. t= (Round to two decimal places as needed.) Identify the P-value P-value= (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test? Since the P-value is than the significance level, CLES the null hypothesis. There OB. Ho Hd 0 H₁ Hg >0 OD. Ho Hd=0 H₁ H<0 sufficient evidence to support the claim of a difference in measurements between the two arms

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). 91 88 82 103 97 108 84 91 The sample mean is x ≈ 93.0. 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 ? = 12.5. The mean glucose level for horses should be ? = 85 mg/100 ml.† Do these data indicate that Gentle Ben has an overall average glucose level higher than 85? Use ? = 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?
