In a study of 205,590 cell phone users, it was found that 38 developed cancer of the brain or nervous system. Assuming that cell phones have no effect, there is 0.000236 probability of a person developing cancer of the brain or nervous system. We therefore expect about 49 cases of such cancer in a group of 205,590 people. Estimate the probability of 38 or fewer cases of such cancer in a group of 205,590 people. What do these results suggest about media reports that cell phone cause cancer of the brain or nervous system. (a) P(x<=38)= (Round to four decimal places as needed)
(b) What does the result from part (a) suggest about the media reports?
A. The media reports appear to be correct because one would expect that more than 38 cell phone users would develop cancer and the study offers some evidence to support this.
B. The media reports appear to be correct because one would expect that less than 49 cell phone users would develop cancer and the study offers some evidence to support this.
C. The media reports appear to be incorrect because one would expect that more than 49 cell phone users would develop cancer. In​ fact, the study may offer some evidence to suggest that cell phone use decreases the probability of developing cancer.

First to answer all gets a donation question 3(multiple choice worth 1 points) (04.01 lc) which of the following levels is lower than cells in the hierarchy of organization of living things? molecules organs organ systems tissues question 4(multiple choice worth 1 points) (04.01 lc) which of these represents an individual form of life such as an animal, plant, or single-celled life form? organ organism organ system tissue question 5(multiple choice worth 1 points) (04.03 lc) what are the green structures inside plant cells where photosynthesis takes place called? chloroplast mitochondrion nucleus vacuole question 6(multiple choice worth 1 points) (04.03 lc) which of the following best matches a part of a living cell with the function it performs? cytoplasm: fluid which carries the nucleus and other organelles vacuole: fluid which carries the nucleus and other organelles cytoplasm: directs all of the cell's activities vacuole: directs all of the cell's activities question 7(multiple choice worth 1 points) (04.03 mc) read the table below. organelles of plant cells present in both plants and animals present in plants but not animals small in animals but large in plants organelle a organelle b organelle c which statement is most likely correct? organelle a is chloroplast, organelle b is cytoplasm, and organelle c is nucleus. organelle a is mitochondrion, organelle b is cytoplasm, and organelle c is nucleus. organelle a is cell wall, organelle b is chloroplast, and organelle c is mitochondrion. organelle a is mitochondrion, organelle b is chloroplast, and organelle c is vacuole. question 8(multiple choice worth 1 points) (04.03 mc) what will most likely happen in the absence of a nucleus? genetic information will not be transmitted by the cell. energy will not be released during cellular respiration. the cell will not store food, water, nutrients, and waste. the cell will lose its shape and structure.
