B. Using functional notation expressed the reaction time if there were nine choices.Calculate the reaction time if there are nine choices around your answer to two decimal places C. If the reaction time is to be at 0.5 seconds, how many choices can there be round your lanswer to the nearest phone number D. If the number of choices increased by a factor of 10, what is the difference in the reaction time round your answer to two decimal places?E. Explain the practical terms what the conceits of the graph means. The graph is increasing and concave down thus as the number of choices blank, then the reaction time blank, but is less and less with each additional choice. ?

For certain decisions, the time it takes to respond is a logarithmic function of the number of choices faced. I One model is given by the following formula where R is the reaction time in seconds and / is the number of choices. + R = 0.17 + 0.44 log N (a) Draw a graph of R versus N. Include values of / from 1 to 10 choices. 1.5. 1.5
