31.75 ounces of pepper
Answer: Option 'b' is correct.
Step-by-step explanation:
Since we have given that
s = 0.81
n = 31
We need to find the 93% confidence interval to estimate the true standard deviation.
degrees of freedom = df = n-1=30
Here, α = 0.93
1-α=0.07
so,
and
So, we will use "Chi square distribution"
So, the interval would be
Hence, 93% confidence interval would be (0.6581,1.058).
Therefore, Option 'b' is correct.
I think the slope is 0 because it doesn't go up or down at all its a straight horizontal line.
I believe the answer is angle DEK. Hope this helps!
