Question

To study the effect of temperature on yield in a chemical process, five batches were produced at each of three temperature levels. The results follow Temperature 50 C 60°C 70°C 29 29 30 34 36 34 39 22 32 26 37 a. Construct an analysis of variance table (to 2 decimals, if necessary). Source of Variation Sum of Squares Degrees of Freedom Mean Square F Treatments Error Total b. Use a .05 level of significance to test whether the temperature level has an effect on the mean yield of the process. Calculate the value of the test statistic (to 2 decimals). The p-value is Select What is your conclusion? Select Check My Work (2

Explanation / Answer

The results of a ANOVA statistical test performed at 20:47 on 21-JUN-2017

The probability of this result, assuming the null hypothesis, is 0.113

TS = 2.627

p-value = 0.113

p-value is more than 0.05 (level of significance )

we reject the null
