True False
- A Miraculin—a protein naturally produced in a rare tropical fruit—can convert a sour taste into a sweet taste. Consequently, miraculin has the potential to be an alternative low-calorie sweetener. In Plant Science (May 2010), a group of Japanese environmental scientists investigated the ability of a hybrid tomato plant to produce miraculin. For a particular generation of the tomato plant, the amount x of miraculin produced (measured in micrograms per gram of fresh weight) had a mean of 105.3 and a standard deviation of 8.0. Assume that x is normally distributed. (a) Find P(x >120).Test whether the correlation (without Northern Ireland) is statistically significant (i.e., significantly different from 0). Report the df and p-value of the testThe results obtained from statistics analysis between the pulse rate at baseline and the pulse rate after smoking using t-test is 0.001, what should be the decision? reject the null hypothesis do not reject the null hypothesis restate the null hypothesis no decision
