Chapter 13: Q. 13.20 (page 532)

13.20 Figure 13.6shows side-by-side boxplots of independent samples from three normally distributed populations having equal standard deviations. Based on these boxplots, would you be inclined to reject the null hypothesis of equal population means? Why?

Short Answer

Expert verified

The null hypothesis of population means can be rejected.

Step by step solution

01

Given information

In the given figure, shows side-by-side boxplots of independent samples from three normally distributed populations having equal standard deviations. Based on these boxplots, would you be inclined to reject the null hypothesis of equal population means

02

Explanation

Examine three normally distributed populations with equal standard deviations in box plots.
The box plots reveal that there is a lot of variety among the sample means in comparison to the variation within the samples.
As a result, the null hypothesis of population means can be rejected.

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).

Consider the following hypothetical samples

a. Obtain the sample mean and sample variance of each of the three samples.

b. Obtain SST, SSTR and SSE by using the defining formulas and verify that the one-way ANOVA identity holds.

c. Obtain SST, SSTR and SSE by using the computing formulas.

d. Construct the one-way ANOVA table.

On what distribution does one-way ANOVA rely?

Breast Milk and IQ. Considerable controversy exists over whether long-term neurodevelopment is affected by nutritional factors in early life. A. Lucas and R. Morley summarized their findings on that question for preterm babies in the publication "Breast Milk and Subsequent Intelligence Quotient in Children Born Preterm (The Lancet, Vol. 339, Issue 8788, Pp, 261-264). The researchers analyzed IQ data on children at age 712-8years. The mothers of the children in the study had chosen whether to provide their infants with breast milk within 72hours of delivery. The researchers used the following designations. Group I: mothers declined to provide breast milk; Group ll a: mothers had chosen but were unable to provide breast milk and Group Il b; mothers had chosen and were able to provide breast milk. Here are the summary statistics on IQ.

At the 1%significance level, do the data provide sufficient evidence to conclude that a difference exists in mean IQ at age 712-8years for preterm children among the three groups? Note: For the degrees of freedom in this exercise:

For an F-curve with df=(6,10), find
