Question

No population standard deviation is known. H_O: µ₀ = 20 grams is assumed. Yet, I believe the average daily consumption of fiber for adults is less than 20 grams per day. In my survey of 457 adults, I found average intake of 19.1 grams with a sample standard deviation of 9.1 (s = 9.1).

Using your TI 83/84 calculator device, find the P-value with the appropriate Hypothesis Test

Use a critical level α = 0.05 and decide to Accept or Reject H_O with the valid reason for the decision.

A. My P-value greater than α Alpha, so I Reject Null Hypothesis

B. My P-value greater than α Alpha, so I Accept Null Hypothesis

C. My P-value less than α Alpha, so I Accept Null Hypothesis

D. My P-value less than α Alpha, so I Reject Null Hypothesis

Answer 1

D. My P-value less than α Alpha, so I Reject Null Hypothesis.
