Drinking tea appears to offer a strong boost to the immune system. In a study of 10 participants, blood samples were taken before and after one week of drinking 5 cups of tea a day (the participants did not drink tea prior to the study) and the levels of interferon gamma were measured, which is a molecule that fights bacteria, viruses, and tumors. The mean production went from 155 pg/mL to 448 pg/mL after drinking tea. The mean difference for the ten subjects is 293 pg/mL (Post-Pre Measurement) with a standard deviation of the differences of 252 pg/mL. Required:
Use the information to test whether mean production of interferon gamma as a response to bacteria is significantly higher after drinking tea than before drinking tea.

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
