A researcher believes that less than 39% of a population has a certain gene. A random sample of 23 people
finds 4 people with that gene. Use a = 0.05.
1. To confirm that the sample is large enough, there must be at least 5 successes and 5 failures. We have a
problem here, since
O There are fewer than 5 successes
On < 30
O There are fewer than 5 failures
nline
We will deal with this in Step 3.
The hypotheses are:
O Ho:p < 0.39; Ha:p > 0.39
O Ho:µ < 0.39; Ha:µ > 0.39
O Ho:µ = 0.39; Ha:µ # 0.39
ver
O Ho:p = 0.39; Ha:p+ 0.39
O Ho:p > 0.39; Ha:p < 0.39
