Answer: Analysis of variance table Response: tmorb Df Sum Sq Mean Sq F value Pr(>F) strain 2 4578.1 2289.03 12.6443 0.0001777 Pesticide 1 653.3 653.33 3.6089 0.0695524 strain pesticide 2 1192.5 596.23 3.2935 0.0544618 Residuals 24 4344.8 181.03 The question is Is there effect on mean time to morbidity pesticide use? The hypothesis test is H0 :μ1 =μ2 =μ3 Versus H1 : μ1 ≠ μ2 ≠ μ3 From Analysis of variance table see that for strain p-value is 0.0001777 is less than 0.05 we reject the null hypothesis Strain is significance to the test and other Pesticide and strain pesticide there p-value is greater than 0.05. Here it is fail to reject the null hypothesis. for strain the critical value is F0.05,2,24 =3.4028 Calculated value is greater than critical value we reject the null hypothesis. So There is significance difference . Similarly, Pesticide and strain Pesticide the critical value is F0.05,1,24 =4.25967721F0.05,2,24 =3.40282611 they are greater than calculated value. So we fail to reject the null hypothesis. There is not significance difference among the population mean of pesticide.

A study was conducted to determine if the performance of a certain type of surgery on young horses had any effect on certain kinds of blood cell types in the animal. Fluid samples were taken from each of six foals an hour after the operation. Suppose that the data on WBC leukocytes follow the normal distribution. One sample Chi-squared test for variancedata: wbcX-squared = 3.5321, df = 5, p-value = 0.3815alternaative hypothesis: true variance is less than 4 Question: Is there evidence to say that the variance of WBC leukocytes is less than 4? State the conclusion based from the results of the test. Choices:- There is no sufficient evidence that the variance of WBC leukocytes is less than 4.- There is a sufficient evidence that the variance of WBC leukocytes is less than 4.

The 99% confidence interval of the difference in population proportions is ( (Round to four decimal places as needed.)
An investigation of the relationship between traffic flow (measured in cars per day) and lead content (measured in micrograms per gram of dry weight) in the bark of trees near the highway yielded the following summary statistics: Sample Mean Sample Standard Deviation Lead Content (micrograms per gram dry weight) y¯=y¯= 680 sysy = 240 Traffic Flow (cars / day) x¯=x¯= 1750 sxsx = 800 The correlation between lead content and traffic flow was found to be r = 0.6 and a scatterplot showed the form to be linear. Since Traffic flow is the X-variable, its mean and standard deviation have been labelled x¯ and sxx¯ and sx. Since Lead content is the Y-variable, its mean and standard deviation have been labelled y¯ and syy¯ and sy .
