Two hundred students were sampled in the College of Engineering. It was found that: 137 take math, 50 take history, 124 take English, 33 take math and history, 29 take history and English, 92 take math and English, 18 take math, history and English. From the given information, there are a. Blank 1 students taking neither math nor history. b. Blank 2 students taking at least 2 subjects. c. Blank 3 students taking no more than one subject.
Suppose we want to estimate the proportion of the Helena population who have used marijuana within the last month. We select 4328 participants and ask them each to first privately draw a card from a standard 52-card deck. If they get a “club” they are asked to respond truthfully to the question “Have you used marijuana within the last month?”If they get any other suit they are asked to respond to the question “Does your phone number end in an odd digit?”The study is blinded in the sense that the researcher doesn’t know which question the participant is answering. Hence, participants are guaranteed anonymity and are more likely to be truthful in their responses. The researchers only get a “yes” or “no” answer from each respondent and don’t know the actual results of the card draw. What is the expected probability of a person’s phone number ending in an odd digit? What is the expected probability of a person’s phone number not ending in an odd digit?

A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 309 people over the age of 55, 77 dream in black and white, and among 309 people under the age of 25, 18 dream in black and white. Use a U.U5 signiticance level to test the claim that the proportion of people over 55 who dream in black and white is greater than the proportion for those under 25 Complete parts (a) through (c) below. Consider the first sample to be the sample of people over the age of 55 and the second sample to be the sample of people under the age of 25. What are the null and alternative hypotheses for the hypothesis test? Identify the test statistic. z= (Round to two decimal places as needed.) Identify the P-value. P-value= (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test? The P-value is ______ the significance level of a = 0.05, so ______ black and white is ____ the proportion for those under 25. There is…
The manager of a theater that is open to residents of two towns, A and B, wants to know if the proportion of households from A that use the library is smaller than the proportion of households from B. In order to test this, the manager asks 45 households in A and 49 households in B whether anyone in their household had used the theater last summer. 23 of the households surveyed in A responded "yes", and 35 of the households in B responded "yes". Find the p-value that would be used to make a conclusion for this hypothesis test.
Regarding the context regarding the coronavirus pandemic, see the table below, which refers to 5 groups of people infected with the coronavirus and the number of deaths in each group. a) You, student, by observing the data tabulated in the table above, come to what conclusion about the absolute frequency of the second grade? b) João, a person observing the table, calculates and states that the relative frequency of the fourth class is 48.46% and informs that 48.46% of the number of deaths occurred in the group with the number greater than or equal to 70 and less than or equal to 80 infected. Do you agree with João's calculation and interpretation? If you agree or disagree, provide the calculation and interpretation that justifies your choice. c) Going deeper, Maria, another person who looks at the table, interprets that 16 deaths occurred in the group with a number greater than or equal to 40 and less than 70 infected people. When you see this interpretation that Maria made, do you…
1a. A recent study (Ackerman, Griskevicius, and Li, 2011) examined expressions of commitment between two partners in a committed romantic relationship. One aspect of the study involved 40 heterosexual couples who were asked about which person was the first to say "I love you." ...the 40 responses were used to see whether the male was more likely to say "I love you" first. 1.c] Write a paragraph, as if to the skeptics and the researchers, describing what your simulation analysis reveals about whether the data provide strong evidence in support of the researchers' conjecture.
