Question 11
The average IQ in the population is 100, however there has been some research into how music changes this. You compared two samples of 300 people listening to either Michael Jackson or Mozart for an hour. You expected that mean IQ score in the Mozart group would be higher than the Michael Jackson group. The mean IQ score in the Mozart group was 130, while for the Michael Jackson group the mean was 90. The standard error across both groups was 4.47.
Calculate the upper boundary of the 95% confidence interval for the sample statistic. The critical t-value for this is 1.96.
