How would you check whether a so-called ‘fair’ die was biased? one way would be to choose a number between 1 and 6—say 3—roll the die a large number of times and see whether or not a 3 shows up roughly 1/6 of the time. think of p as the (unknown) probability that this die will show a 3 when rolled.

(a) write a down the null and (two-sided) alternative hypotheses.
(b) you intend to roll this die 400 times. verify that the two validity conditions are met in this case.
(c) of the 400 rolls, a 3 came up 51 times. compute zo and hence the p-value.
(d) write the statistical conclusion. write the contextual conclusion.
(e) compute a 95% confidence interval for p and use your interval to test the null hypothesis specified in part (a). write your statistical conclusion. is it the same as in part (d)?
(f) what is the implicit level of significance in part (e)?

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.
