Step 1 From the two-way table , the total number of females prefers prefer an SUV and Sedan is 180 Step 2 The number of female prefers Sedan is 45 Therefore , the number of female prefers an SUV is 180-45=135 Conditional relative frequency for the Female prefers an SUV is \(\frac{\text{Number of female prefers an SUV}}{\text{Total number of Female}}\)
\(\text{Conditional relative frequency}=\frac{135}{180}\)
\(=0.75\) Hence , the option (c) is correct

1. Who seems to have more variability in their shoe sizes, men or women?
a) Men
b) Women
c) Neither group show variability
d) Flag this Question
2. In general, why use the estimate of \(n-1\) rather than n in the computation of the standard deviation and variance?
a) The estimate n-1 is better because it is used for calculating the population variance and standard deviation
b) The estimate n-1 is never used to calculate the sample variance and standard deviation
c) \(n-1\) provides an unbiased estimate of the population and allows more variability when using a sample and gives a better mathematical estimate of the population
d) The estimate n-1 is better because it is use for calculation of both the population and sample variance as well as standard deviation.
