A researcher is interested in species diversity of two different wetland areas. She claims that wetland 1 has higher species diversity than wetland 2. Assume the population standard deviations are known and the test statistic is calculated to be Z = 2.98. Find the p-value for testing the researcher's claim. 0.0282 0.5000 0.9986 0.0014 0.0028

A sample of the thickness (in hundreths of an inch) of 15 pieces of Fruit Flavored Bubble Gum yielded a sample mean of 6.841 and a standard deviation of 0.155. A second independent sample of the thickness of 10 pieces of Fruit Flavored Gum yielded a sample mean of 6.701 and standard deviation of 0.108. A researcher claims that Fruit Flavored Bubble Gum should be thicker on average than Fruit Flavored Gum because bubble gum has more elasticity than regular gum. Assume both distributions are normally distributed. Which test statistic is appropriate for testing the researcher's claim?
