Since the significance level is set at 5%, then the probability of the result will be 3.6%.

What is the probability case about?

Probability is known to be defined as the outcome or the measurement of the idea that an event may or may not occur. The probability of the treatment group’s mean is said to be bigger than the control group’s mean by 8 points or more and thus, it will be:

= (26 + 8 + 2)/1000

= 36/1000

= 0.036

Therefore, since the significance level is set at 5%, then the probability of the result will be 3.6%.

This can be interpreted as " There was a statistically significant  due to the fact that the probability of the difference is said to be less than 5% of the significance level or one can say that:

Since the significance level is set at 5%, and the probability of the result is 3.6%, this is said to be less than the significance level and as such, the result is statistically significant.
