Complete the table below to show the relative frequencies of the data in the first row.
enter numbers in the boxes as the decimals to the hundredth place.

category 1;
group 1: 30
group 2: 90

category 2;
group 1: 14
group 2: 32

The relative frequency of group 1=

The relative frequency of group 2=

Step-by-step explanation:

The total numbers in the first row =

Group 1: 30

The relative frequency of group 1=

∴The relative frequency of group 1=

Similarly, Group 2: 90

The relative frequency of group 2=

∴The relative frequency of group 2=

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;

the answer to question 1 is -8, 28.
