The proportion of students in a psychology experiment who could remember an eight-digit number correctly for t minutes was 0.9 − 0.4 ln(t) (for t > 1). find the proportion that remembered the number for 7 minutes. (round your answer to one decimal place.)

The proportion would be 0.1

Step-by-step explanation:

Given, the function that shows the proportion of students in a psychology experiment who could remember an eight-digit number correctly for t minutes,

If t = 7 minutes,

Hence, the proportion that remembered the number for 7 minutes is 0.1 ( approx )
