To investigate whether or not sexism was present in the workplace, 48 male bank supervisors were each given a personnel file and asked to judge whether the person represented in this file should be recommended for promotion or whether the person's file should be held. the files were identical except that half of the files were labeled male and the other half female. the data is summarized below.

The correct options are:

Step-by-step explanation:

Joint Frequency--

The entries that are present in common of two conditions i.e. the number of times the combination of two conditions comes.

Marginal Frequencies--

The entries that are present in the total row or total of column entries are called marginal frequencies.

From the table we could see that the entries in the pink box are joint frequency and in the blue columns are  marginal frequency.

Hence,

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this

true
