So the pencils all together would be $6 so divide that by 3 and you get D as your answer each pencil costs $2
Yes, there is statistical evidence that the drug is effective in reducing infarct size because p-value is less than the significance value.
<h3>
How to find hypothetical Evidence?</h3>
Let us first define the hypotheses;
Null Hypothesis; H₀: µ = 25
Alternative Hypothesis; H₁: µ < 25
Standard Deviation; σ = 10
Sample mean; x' = 16
Sample size; n = 8
z-score is;
z = (16 - 25)/(10/√8)
z = -2.55
From online z-score table, the p-value is 0.005
Since p-value is less than the significance value, then we reject the null hypothesis and conclude that the drug is effective in reducing infarct size.
