To answer this item, we let x represent the original price of the object or the fridge before it happened.
The representation would lead us to conclusion that the total amount to be paid is equal to,
1.20x = £480
The value of x from the equation,
x = 400
The answer is <span>£</span>400

Step-by-step explanation:
let a be the number of tennis balls.
let b be the number of tennis rackets.
We write determine the ratio of balls to rackets by dividing the number of balls by the number of rackets:
For every one ball, there 5 thirds of a racket.
We plot this function on a graph to visualize our model;

Answer:
- A. Paired-sample t-test. --- Wilcoxon Signed-Ranks T test
- B. Independent-sample t-test. --- Mann-Whitney U test
- C. One-way ANOVA, independent samples. --- Kruskal-Wallis H test
- D. One-way ANOVA, repeated measures. --- Friedman test
Step-by-step explanation:
- The nonparametric statistics is a branch of statistics, that seeks out the population distribution that is either being distributed freely or specifically.
- Wilcoxon Signed-Ranks T-test is a hypothesis test used to compare the two or pre related columns that can be matched and maybe a repeated measure on a single sample.
- The Mann-Whitney U test is a null hypothesis and states the probability of a random sample of X and Y from the population is greater than the X and that Y is greater than X.
- Kruskal-Wallis H test is a test of one variance analysis and tests that sample originates from the same distribution.
- The Friedman test is used to find treatment across multiple tested attempts. It involves the ranking of the rows and then considering the values of the column.
