Question

Gentle Ben is a Morgan horse at a Colorado dude ranch. Over the past 8 weeks, a veterinarian took the following glucose reading from the horse (in mg/100 mg).

92  87  82  107  99  109  85  89

The sample mean x-bar is 93.8. Let x be a random variable representing glucose readings taken from gentle Ben.  We may assume x has a normal distribution, and we know from past experience that the standard deviation = 12.5. The mean glucose level for horses should be mu = 85mg/100gl.  Do these data indicate that gentle Ben have a overall average glucose level higher than 85? Use alpha = 0.05

A- Compute z value of the sample stasistic test. Round answer to 2 decimal places

B- Find (or estimte) the P-Value . Round answer to 4 decimal places

I get 1.99 for the z value but cannot come up with correct p-value.

Step 1

Given data of glucose reading for 8 weeks
92 87 82 107 99 109 85 89
The sample x-bar is 93.8 .
x is normal distribution with standard deviation = 12.5

Given that the mean glucose levelfor horses is µ = 85 mg/100gl
claim is that to see if the gentle Ben have glucose level higher than 85 at 0.05 level of significance.
