The bacterial strain acinetobacter has been tested for its adhesion properties, which is believed to follow a normal distribution. a sample of five measurements gave readings of 2.69, 5.76, 2.67, 1.62 and 4.12 dyne-cm. assume that the standard deviation is known to be 0.7 dyne-cm_2 and that the scientists are interested in high adhesion (at least 2.66 dyne-cm^2)(a) should the alternative hypothesis be one-sided or two-sided? write down the null and alternative hypotheses.(b) based on your answer to part (a), test the hypothesis to see if the mean adhesion is at least 2.66 dyne-cm_2 (use the p-value approach) what can be concluded?
