Which of the following situations would result in a t-test that not likely to be accurate? Choose all that apply

a. data sets that had normal distributions

b. a comparison of means in which one sample set had 10 measurements and the other had 30 measurements

c. a sample size of 5 a sample size of 50 sample

d. sets that differed in variance

e. a comparison of means in which one sample set had 37 measurements and the other had 41 measurements

The correct options are (c) and (d).

Explanation:

The assumptions made before using a t-distribution for a hypothesis test are:

A sample size of 5 a sample size of 50 sample will not be accurate for a t-test because on of the sample size is, 5.

This sample size is very small and when plotted will not follow a normal distribution.

The sets that differed in variance will not be accurate for a t-test because for using a t-test homogeneity of variances is assumed.

Thus, the correct options are (c) and (d).

protist eukaryotes that are not plants, animals, or fungi ("misfits")

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
