An instructor is interested in assessing students' typing speedin the class. He knows that the average at the university is 49word per minute (wpm) with a SD of 18 wpm. He collectsdata from 31 of his students.
a) What is the probability of the average typingspeed being less than 49 wpm?
probability =Ă‚Â Ă‚Â
b) What is the proability of the average typingspeed being between 51 and 53 wpm?
probability =Ă‚Â Ă‚Â
Note: Do NOT input probability responses aspercentages; e.g., do NOT input 0.9194 as 91.94.
