of row relative freguencies below shows the results of a survey about food preference for pets. Pets and Food Preference Prefer Dry Food Prefer Wet Food Total Dog 0.31 0.69 1.00 Cat 0.30 0.70 1.00 Based on the row relative frequencies in the table abovw, which statement is true? A. There is an association between type of pet and food preference because the row relative frequencies are similar fo dog and cat rows. B. There is an association between type of pet and food preference because the row relative frequencies are not similar for the dog and cat rows. C. There is not an association between type of pet ands food preference because the row relative frequencies are similar for the dog and cat rows. D. There is not an association
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
The two-way table of row relative freguencies below shows the results of a survey about food preference for pets.
Pets and Food Preference
| Prefer Dry Food | Prefer Wet Food | Total | |
| Dog | 0.31 | 0.69 | 1.00 |
| Cat | 0.30 | 0.70 | 1.00 |
Based on the row relative frequencies in the table abovw, which statement is true?
A. There is an association between type of pet and food preference because the row relative frequencies are similar fo dog and cat rows.
B. There is an association between type of pet and food preference because the row relative frequencies are not similar for the dog and cat rows.
C. There is not an association between type of pet ands food preference because the row relative frequencies are similar for the dog and cat rows.
D. There is not an association between type of pet and food preference because the row relative frequencies are not similar for the dog and cat rows.
