Final answer:
The hypothesis test conclusion will be to fail to reject the null hypothesis.
Step-by-step explanation:
The conclusion that will result from the hypothesis test, given a 95% confidence interval for μ of [10, 15], is a) Fail to reject the null hypothesis. This means that there is not enough evidence to conclude that the true population mean is different from the null hypothesis value.
The confidence interval provides a range of values within which we can be reasonably sure the true population mean lies, but it does not indicate a statistically significant difference from the null hypothesis value.
