(b) See the table below

(c) What percentage of men older than 30 had facial hair? 50%

Explanation:

(a) Create a two-way table of the data

Count the number of men in each group

Put the information in the two-way table:

                                    Has Facial Hair        No Facial Hair      Total

Older than 30                       3                             3                       6

30 and younger                    4                            2                        6

Total                                       7                             5                       12

i) Of the men surveyed how many were 30 and younger?

ii) Of the men surveyed how many men did not have facial hair:

(b) Create a two way relative frequency table that displays the relative frequencies

Determine each relative frequency divide each cell by the total number of men of the sample, 12:

Put the relative frequencies in the table:

                                    Has Facial Hair        No Facial Hair      Total

Older than 30                     0.250                        0.250           0.500

30 and younger                 0.333                         0.167             0.500

Total                                     0.583                        0.417             1.000

(c) What percentage of men older than 30 had facial hair?

This is a conditional probability. You must divide the relative frequency in the intersection of the men older than 30 and has facial hair, which is 0.250 by the relative frequency of total men older than 30, which is 0.500.

Thus, this is 0.250/0.500 = 0.500.

Now, convert to percent: 0.500 = 50.0%

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.
