Question
Use Megastat and Data Analysis to corroborate your answers. ANOVA: There are 5 pharmaceutical companies that produce 9 types of generics. The Consumers want to know which firm has the highest average prices Not to buy their products. The prices (US dollar) are presented below: 1. Variability between samples (CMTR). Use the corresponding formula. 2. Variability within samples (CME). Use the corresponding formula. 3. The F-calculated (test statistic) and the P-value. 4. Is the null hypothesis rejected at 5% level of significance. [Use P-value method and test statistic method]. 5. Explain your result with confidence intervals. [Use 99% level Of confidence] 6. Can the consumer know which pharmacy should not choose or which to choose? Explain.Explanation / Answer
One-way ANOVA: A, B, C, D, E
Source DF SS MS F P
Factor 4 494.6 123.6 2.49 0.059
Error 40 1988.7 49.7
Total 44 2483.2
S = 7.051 R-Sq = 19.92% R-Sq(adj) = 11.91%
a) between variablity = 494.6
b) within variabity = 1988.7
c) F-statistics=2.49 and p-value = 0.059
d) since p-value=0.059>0.05=significance level we are fail to reject hypothesis that the groups are diferent. at 95% level of confidence we can say that the groups are same effective.
e) since p-value=0.059>0.01=significance level we are fail to reject hypothesis that the groups are diferent. at 99% level of confidence we can say that the groups are same effective.
f) here at 95% or 99% level of significance there is no chance of giving preference to ant gropus
