Question 56100
using the formula R=0.17 + 0.44 log N, determine how many choices would result in a reaction time of 0.42 seconds. Round your answer to the nearest whole number. I started the formula as: 
.42=0.17 + 0.44 log N 
0.42-0.17 = 0.44log N
0.25=0.44log N
log N = 0.56818181...
N=10^0.56818181...
N=3.699830414...
