Question

Does listening to Mozart lead to higher scores on an IQ test? An experiment involved listening to Mozart while performing abstract reasoning skills on an IQ test. These results were compared to the completion of similar tasks with a silent background. The mean IQ scores were 1.2 points higher after listening to Mozart than with the silent background. The p-value for the test was calculated to be 0.0004. Can we conclude that listening to Mozart will lead to much higher scores on IQ test?

Answer 1

$H_0:\mu = 1.2$

$H_1:\mu > 1.2$

Since, p-value is 0.0004 which is even less than 0.01 so, Data is statistically significant

. Reject the null hypothesis Ho

So, we can conclude that listening to Mozart will lead to much higher scores on IQ test.
