A noted psychic was tested for extrasensory perception. The psychic was presented with200 cards face down and asked to determine if each card were one of five symbols: astar, a cross, a circle, a square, or three wavy lines. The psychic was correct in 50 cases.Let p represent the probability that the psychic correctly identifies the symbol on thecard in a random trial. Assume the 200 trials can be treated as a simple random samplefrom the population of all guesses the psychic would make in his lifetime. How large asample n would you need to estimate p with a margin of error of 0.01 with 95%confidence? Use the hypothesized value p= 0.20 as the value for p'.A) n=32В)С) п36147D) п%3D9604n == 1537

It is given that margin of error (E) is 0.01 and the confidence level is 95%.

A researcher studies the effects of guilt on memory. First, subjects perform a very boring task for one hour. Then each subject is instructed to tell the next subject either (a) that the experiment took one hour and they found it very boring, or (b) that the experiment took one hour and was very interesting. After that, each subject is asked to study a list of words and are tested on memory for the list. 30 subjects are randomly assigned to one of the two conditions. In order to see whether the experimental manipulation has any effect on memory, which would be the proper statistical test? A)a related sample t-test-test   B)an independent sample t-test   C)a z test   D)a one sample t
A multiple-choice test has nine questions. For each question there are four possible answers from which to select. One point is awarded for each correct answer, and points are not subtracted for incorrect answers. The instructor awards a bonus point if the students spell their name correctly. A student who has not stud- ied for this test decides to choose an answer for each question at random.a. Find the expected number of correct answers for the student on these nine questions.b. Find the standard deviation of the number of correct answers for the student on these nine questions.c. The student spells his name correctly:i Find the expected total score on the test for this student.ii Find the standard deviation of his total score on the test.

After once again losing a hockey game to the Michigan Tech,the alumini association of NMU conducted a survey to see if alumini were in favour of firing the coach.A simple random sample of 100 alumini from the population of all living alumini was taken .Sixty-four of the alumini in the sample were in favour of firing the coach.Let p represent the proportion of all living alumini who favor firing the coach. what is a 99% confidence interval for p?
In a memory test, the test subjects are given a large number and are asked to memorize it. Historical records show that 80% of test subjects pass the test. To pass the test, a subject must exactly repeat all the digits in the number after two hours. A random sample of 625 people to take the memory test is going to be chosen. Let p be the proportion of people in the sample who pass the test. Answer the following. (If necessary, consult a list of formulas.) (a) Find the mean of P. 0 (b) Find the standard deviation of p. 0 (c) Compute an approximation for P(P >0.84), which is the probability that more than 84% of the people in the sample pass the test. Round your answer to four decimal places. 0 X

The University of Chicago's General Social Survey (GSS) is the nation's most important social science sample survey. For reasons known only to social scientists, the GSS regularly asks a random sample of people their astrological sign. Here are the counts of responses from a recent GSS of 4344 people: Sign Aries Taurus Count 321 360 Sign Libra Scorpio Count 392 329 Gemini 367 Sagittarius 331 Cancer 374 Capricorn 354 Leo 383 Aquarius 376 Virgo 402 Pisces 355 We want to test Ho: All 12 astrological signs are equally likely versus Ha: All 12 astrological signs are not equally likely. Use a chi-square goodness-of-fit test to compute a test statistic and P-value. Do these data provide convincing evidence at the 1% significance level that all 12 signs are not equally likely? Because the P-value of 0.6562 > 0.05, we cannot reject the null hypothesis. We cannot conclude that all 12 signs are not equally likely. Because the P-value of 0.0487 > 0.01, we cannot reject the null hypothesis. We…
A surveyor wants to sample a city for the local Public Health Office in order to assess asthma rates annually. In order to get the best estimate for the project, the surveyor first decides to sample 2 of 15 census tracts, and then to sample 5 households from each tract. Assume there are only 10 households in each tract. The surveyor randomly assigns each tract in the city a number 01-15, and each household in each tract a number 01-10. Use the following random number table to select each tract, and then each household, continuing along the line. 058791 211403 098746 170528 086401 370614 097810 036418 340514 A) What kind of sampling strategy is this? B) Which census tracts and households will be selected?
A group of 11 students was selected at random and asked for their high school GPA and their freshmen GPA in college the subsequent year. The results were: Student High School GPA Freshmen GPA 1 2.0 1.6 2 2.2 2.0 3 2.6 1.8 4 2.7 2.8 5 2.8 2.1 6 3.1 2.0 7 2.9 2.6 8 3.2 2.2 9 3.3 2.6 10 3.6 3.0 We would like to know whether there is a linear relationship between the high school GPA and the college freshmen GPA, and we would like to be able to predict the freshmen GPA, if we know that the high school GPA of another student is, say, 3.4. Provide the two requested scatter plots for this data (put college freshman GPA on the Y (vertical) axis!). a) What would be your approximate 95% prediction interval for question (g)? b) Show your scatterplot with the predicted trend line below
A Statistics instructor wishes to know the average age (in month) of his 200 students. He decides to choose 25 students from the class and ask them for their age. All 200 names are put in a hat and 25 names are then chosen at random (without replacement). The average age of the students chosen is observed to be 231 months. The group of 25 students is known as what?
