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 82 107 97 108 82 89 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 6 = 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 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: M = 85; H1: H # 85; two-tailed O Ho: H = 85; H1: H > 85; right-tailed O Ho: M > 85; H1: M = 85; right-tailed O Ho: M = 85; Him
