Fresh Roses A horticulturalist devised a scale to measure the freshness of roses that were packaged and stored for varying periods of time before transplanting. The freshness measurement y and the length of time in days that the rose is packaged and stored before transplanting x are given below.
a. Fit a least-squares line to the data.
b. Construct the ANOVA table.
c. Is there sufficient evidence to indicate that freshness is linearly related to storage time? Use α = .05.
d. Estimate the mean rate of change in freshness for a 1-day increase in storage time using a 98% confidence interval.
e. Estimate the expected freshness measurement for a storage time of 14 days with a 95% confidence interval.
f. Of what value is the linear model when compared to ̅y in predicting freshness?
