As per independent t-test, t(48) = -3.94; p= 0.000. Since the p-value is less than the critical alpha value of 0.05, there is a significant difference in IQ between the genders. IQ of the female is higher than that of the male.

As per Pearson’s correlation (r) = 0.158; p = 0.272. A positive correlation coefficient shows a positive association between age and IQ.
