- The following problem submitted by Daniel Hahn of Blairstown, Iowa, appeared in the Ask Marilyn column of Parade magazine. Source: Parade magazine. You discover two booths at a carnival. Each is tended by an honest man with a pair of covered coin shakers. In each shaker is a single coin, and you are allowed to bet upon the chance that both coins in that booths shakers are heads after the man in the booth shakes them, does an inspection, and can tell you that at least one of the shakers contains a head. The difference is that the man in the first booth always looks inside both of his shakers, whereas the man in the second booth looks inside only one of the shakers. Where will you stand the best chance?A Bitter Dispute With the publication of Ars Magna, a dispute intensified between Jerome Cardan and another mathematician named Niceolo Fontana, otherwise known as Tartaglia. What was the dispute, and how did it arise? In your opinion, who was at fault? Write a paragraph or two about your findings.I need help with part b the null and alternative hypotheses for both H0 and H1 please
- A researcher is interested in differences among blondes, brunettes, and redheads in terms of introversion/extroversion. She selects random samples from a college campus, gives each subject a test of social introversion, and comes up with the following: 1.

Pansies are not purple.(A) Null hypotheses cannot be made with non-normal data. (B) Alternative hypotheses cannot be made with non- normal data. O Both statements are true. O Only the first statement (A) is true. O Only the second statement (B) is true. O None of the statements are true. 3
- if any, can be reached from the given hypotheses and justify your answer. Some flowers are red. Some flowers are purple. Pansies are flowers.If the claim is allied with the null hypotheses, can we ‘prove’ that the claim is true? Why or why not?Researchers found 400 current smokers to volunteer for a study in which each was randomly assigned to one of three treatment groups. Group 1 received an electronic cigarette (e-cig) in which each cartridge contained 7.2 mg of nicotine, Group 2 received an e-cig that contained 5.4 mg of nicotine, and Group 3 received an e-cig that contained no nicotine. The subjects did not know which group they were assigned. During the course of the intervention, subjects dropped out of the study. At the end of the study 82 subjects remained in Group 1, 77 in Group 2, and 69 in Group 3. Results as to whether the subject quit smoking entirely are available below. Complete parts (a) through (g).

- A teacher believes that 85% of students in the 2nd grade at her school will want to go to the zoo. However, she also thinks that rain would cause that percentage to get much lower. When the day comes to go to the zoo it is raining, and only 79% of the students want to go to the zoo. Which set of hypotheses should this teacher test? O HO: p = 0.85 Ha: p does not equal 0.85 O HO: p = 0.85 Ha: p = 0.79 O HO: p does not equal 0.85 Ha: p = 0.85 HO: p = 0.85 Ha: p < 0.852. To test whether memory changes with age, a researcher conducts an experiment in which there are four groups of six subjects each The groups differ according to the age of subjects. Each subject is shown a series of nonsense syllables. The subject is then asked to free recall the syllables. The number of syllables remembered by each subject is shown below. ever 30 years old 14 40 years old 12 50 years old 17 60 years old 13 15 14 10 13 erd 15 16 14 7 17 11 8 12 12 13 6. 10 18 15The national average SAT score is roughly 1500.
