A certain data set had an IQR of -3.45 (negative 3.45). Which of the following must be true about the statement above? Group of answer choices The statement is false because IQR, being a measure of spread, can never be negative. The statement could be true because it is possible for an IQR to be greater than -5. (negative 5). The statement could be true, we don’t have the data set being referred to, so we can’t say if the IQR is or is not -3.45. The statement is false because it is highly unlikely for the digits to be consecutive like that (3 then 4 then 5).

Question 2 (2pts): You are studying the OLF1 gene which encodes a neuron-specific transcription factor involved in regulating gene expression in neurons (brain cells) in humans. The OLF1 transcription factor is highly expressed in neurons but not in other cell types. AC5 is another gene that encodes a transcription factor that binds to an enhancer sequence of the OLF1 gene and positively regulates expression of OLF5. miR246 is a microRNA that directly regulates expression of AC5. In humans, a muscle cell does not have the OLF1 gene (Irue or false) In human neurons, the OLF1 gene is likely in a region with decreased levels of histone acetylation (true or false) Which cell type would you predict to find high levels of methylation of the promoter sequence of AC5? (neurons or muscle cell) Which cell type would you predict to find the gene encoding miR246 in a region with high levels of histone acetylation? (neurons or muscle cell)

According to one association, the total energy needed during pregnancy is normally distributed, with mean $ \mu=2600 \frac{\mathrm{kcal}}{\text { day }} $ and standard deviation $ \sigma=50 \frac{\mathrm{kcal}}{\mathrm{day}} $. (a) Is total energy needed during pregnancy a qualitative variable or a quantitative variable? (b) What is the probability that a randomly selected pregnant individual has an energy need of more than 2625 kcal $ \frac{\mathrm{kcal}}{\text { day }} $ ? Interpret this probability. (c) Describe the sampling distribution of $ \bar{x} $, the sample mean daily energy requirement for a random sample of 20 pregnant individuals. (d) What is the probability that a random sample of 20 pregnant individuals has a mean energy need of more than $ 2625 \frac{\mathrm{kcal}}{\text { day }} $ ? Interpret this probability. (a) Choose the correct answer below. Qualitative Quantitative (b) $ P(X>2625)= $ $ \square $ (Round to four decimal places as needed.)
