(20 pts) Below is the output (units of statistical tests comparing rates o f carbon dioxide (CO) production - mi per of sucrose. Based on the following results of hour) by bread yeast in the presence of three different concentrations statistical tests and graphs provided, answer questions 12a-12i, which begi(B) in on the next page 1.5 -0.5 0.0 0.5 1.0 1.5 N 18 Bandwidth= 06694 norm quantiles 0 0.25 0.5 Sucrose co2_rate hr Shapiro-Wilk normality test w 0.90298, p-value 0.2698 Bartlett's K-squared -6.098 df= 2, p-value 0.04741 Levene's Test One-way ANOVA Df F value Pr (>E) Df Sum Sq Mean Sq F value Pr(OF) Sucrose 2 22.831 11.415 7.252 0.0251 group 2 1.2747 0.3456 Residuals 6 9.445 1.57 Kruskal-Wallis chi-squared = 5.4222, df-2, p-value 0.06646 Questions appear on next pageExplanation / Answer
(a) (A) normal probability(B)Q-Q plot (C) box-plot (D) histogram
(b) there are 9 samples,
(c) independent variable is concentration of sucrose and dependent variable is carbon di oxide
(d) level of factor variable is 3
(e) null hypothesis H0: effect of all sucrose leves are same
alternate hypothesis H1: atleast one level of sucrose is different to others
(f) test statistic F=7.252, df( df1=2 and df2=6), P-value =0.0251
(g) here level of significance alpha is not given, let alpha=0.05( generally alpha=0.05 is taken)
since p-value is less than alpha=0.05, so we fail to accept H0 and reject H0
(i) since p-value is less than alpha=0.05, so we fail to accept H0 and reject H0
