Question
b. Suppose you assume that 14.5% of those invited will attend, and so you rent 508 chairs (because 0.145 times 3500 is 507.49999999999994). What is the approximate probability that more than 14.5% of those invited will show up and you will not have enough chairs? Refer to the TI-83/84 output given. Recall that this gives the Normal cumulative probability in the following format: Normalcdf (left boundary, right boundary, mean, standard deviation) normalcdf (0.145, 1 , 0.14, 0.00586515) 0.1969702291 Using a the output given above, what is the approximate probability that more than 14.5% of those invited will show up and you will not have enough chairs? (Round to four decimal places as needed.)Explanation / Answer
from above output is for probability of getting more than 14.5% of those invited.
therefore approximate probability =0.1970
