The bacterial strain Acinetobacter has been tested for its adhesion properties. A sample of five measurements gave readings of 2.69, 5.76, 2.67, 1.62 and 4.12 dyne-cm2. Assume that the standard deviation is known to be 0.66dyne-cm2 and that the scientists are interested in high adhesion (at least 2.5 dyne-cm2).

(a) Should the alternative hypothesis be one-sided or two-sided?

(b) Test the hypothesis that the mean adhesion is 2.5 dyne-cm2.

(c) What is the P -value of the test statistic?
