An individual receives a iq score of 73. taking into account standard error of measurement (sem), what is his "true score" 95 percent of the time of test-retest reliability is .96

It's saying that 95% of the time the comparison from test to retest is 96% reliable.

so I would take (0.95+0.96)÷2= 0.955

then 73×0.955=69.715

then 73-69.715=3.285

so I would range the possible true score between 69.715 and 76.285

also written as 73 ± 3.285
