Question

6. In a study of the relationship of the shape of a tablet to its dissolution time. 6 disk-shaped ibuprofen tablets and 8 oval-shaped ibuprofen tablets were dissolved in water. The dissolve times, in seconds, were as follows: Disk: 269.0, 249.3, 255.2, 252.7, 247.0, 261.6 oval: 268.8, 260.0, 273.5, 253.9, 278.5, 289.4, 261.6, 280.2 Can you conclude that the mean dissolve times differ between the two shapes? Conduct a hypothesis test at the oc 5% level. (a) State the appropriate null and alternative hypotheses. (b) Compute the test statistic. (c) Compute the P-value (d) state the conclusion of the test in the context of this setting.

Explanation / Answer

From the given data, we have

p-value = 0.0149

As p-value is less than significance level of 0.05, we reject null hypothesis. this means there is difference in the mean of dissolve times of two tablets.

Null Hypothesis Alternate Hypothesis H0: 1 = 2 Ha: 1 2
