Short Answer

Expert verified

(a)F0.05=3.22

(b)F0.01=5.39

(c)F0.025=4.07

Step by step solution

01

Part (a) Step 1: Given information

Given in the question that, An F-curve has df=(12,5). We need to flndF0.05.

02

Part (a) Step 2: Explanation

Given: An F-curve hasdf=(6,10)

The area to the right of 0.05F-value

Calculation:

The numerator's degrees of freedom are =6.

The denominator's degrees of freedom are =10.

α=0.05significance level

The F-value is calculated using Table VIII. Scroll down to'6'in the dfd column. After that, concentrate on the α0.05 row. Cross that row to the '10' column, and the point earned will be 3.22.

Therefore,F0.05=3.22

03

Part (b) Step 1: Given information

Given in the question that, An F - curve has df=(12,5). We need to flnd F0.01.

04

Part (b) Step 2: Explanation

Given: df=(6,10)on an F-curve

The area immediately to the right of the F-value =0.01.

The numerator's degrees of freedom are =6.

The denominator's degrees of freedom are =10.

α=0.01significance level

The F-value is calculated using Table VIII. Scroll down to'6'in the dfd column. After that, concentrate on the αrow labelled 0.01. Cross that row to the '10' column, and the point earned will be 5.39

Therefore,

F0.01=5.39

05

Part (c) Step 1: Given information

Given in the question that, An F - curve has df=(12,5). We need to find F0.025.

06

Part (c) Step 2: Explanation

Given: df=(6,10)on an F-curve

The area to the right of =0.025F-value

The numerator's degrees of freedom are =6.

The denominator's degrees of freedom are =10.

α=0.025significance level

The F-value is calculated using Table VIII. Scroll down to'6'in the dfd column. Next, concentrate on the 0.025column for α. The point acquired will be 4.07if you go across that row to the column labeled'10 '.

Therefore,

F0.025=4.07

Vitamin C (ascorbate) boosts the human immune system and is effective in preventing a variety of illnesses. In a study by E. Cameron and L. Pauling, published as the paper "Supplemental Ascorbate in the Supportive Treatment of Cancer; Reevaluation of Prolongation of Survival Times in Terminal Human Cancer", patients in advanced stages of cancer were given a vitamin C supplement. Patient were grouped according to the organ affected by cancer; stomach, bronchus, colon, ovary or breast. The study yielded the survival times, given on the WeissStats site.

a. Obtain individual normal probability plots and the standard deviations of the sample.

b. Perform a residual analysis

c. use your results from part (a) and (b) to decide whether conducting a one-way ANOVA test on the data is reasonable. If so, also do parts (d) and (e).

d. use a one-way ANOVA test to decide, at the\(5%\) significance level whether, the data provide sufficient evidence to conclude that a difference exists among the means of the populations from which the samples were taken.

e. Interpret your results from part (d).

a. Obtain individual normal probability plots and the standard deviations of the samples.

b. Perform a residual analysis.

c. Decide whether presuming that the assumptions of normal populations and equal standard deviations are met is reasonable.

Fish of Lake Laengelmaevesi. An article by J. Puranen of the Department of Statistics, University of Helsinki, discussed a classic study on several variables of seven different species of fish caught in Lake Laengelmaevesi, Finland. On the Weiss Stats site, we present the data on weight (in grams) and length (in centimeters) from the nose to the beginning of the tail for four of the seven species. Perform the required parts for both the weight and length data.

a. Obtain individual normal probability plots and the standard deviation of the samples.

b. Perform a residual analysis.

c. Use your results from parts (a) and (b) to decide whether conducting a one-way ANOVA test on the data is reasonable. If so. also do parts (d) and (e).

d. Use a one-way ANOVA test to decide, at the 5%significance level, Whether the data provide sufficient evidence to conclude that a difference exists among the means of the populations fewer than the samples were taken.

Income by Age. The U.S. Census Bureau collects information on the incomes of employed persons and publishes the results in Historical Income Tables. Independent simple random samples of 100cm- ployed persons in each of four age groups gave the data on annual income, in thousands of dollars, presented on the WeissStats site.
