Mathematics
1 answer:
statuscvo [17]3 years ago
8 0

You can find the mean of negative numbers just the same as for positive numbers. It doesn't hurt for the mean to be negative.

For example, with the number -9, -5, -4, -3, -1 you can find the mean jsut as any other numbers

-9+-5+-4+-3+-1=-22

-22/5=-4.4

the mean for those set of numbers is -4.4

A topic or recent clinical interest is the possibility of using drugs to reduce infarct size is patients who have myocardial inf
Elanso [62]

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.
