Claim: Most adults would not erase all of their personal information online if they could. A software firm survey of 524 randomly selected adults showed that 38% of them would erase all of their personal information online if they could. Complete parts (a) and (b) below. A. Express the original claim in symbolic form. Let the parameter represent the adults that would erase their personal information. B. Identify the null and alternative hypotheses.
2 You are asked to perform a hypothesis test that population mean is at most, or no greater than, 85. Which of the following is the correct statement of the null and alternative hypotheses for this test? a H₀: µ ≥ 85 H₁: µ < 85 b H₀: µ ≤ 85 H₁: µ > 85 c H₀: µ > 85 H₀: µ ≤ 85 d H₁: µ < 85 H₀: µ ≥ 85
In a certain survey, 508 people chose to respond to this question: "Should passwords be replaced with biometric security (fingerprints, etc)?" Among the respondents, 53% said "yes." We want to test the claim that more than half of the population believes that passwords should be replaced with biometric security. Complete parts (a) through (d) below. %3D a. Are any of the three requirements violated? Can a test about a population proportion using the normal approximation method be used? O A. The conditions np 25 and nq 25 are not satisfied, so a test about a population proportion using the normal approximation method cannot be used. O B. The sample observations are not a random sample, so a test about a population proportion using the normal approximating method cannot be used. O C. One of the conditions for a binomial distribution are not satisfied, so a test about a population proportion using the normal approximating method cannot be used. O D. All of the conditions for testing a…

f) The superintendent of Hospital 2 performed the Goodness of Fit Test to test whether 30% of the patients go to Hospital 1, 15% of the patients go to Hospital 2 and 55% of the patients go to Hospital 3. Given: The superintendent found that the p-value for the test is 0.00218. Let: Pi = be the proportion of patients at Hospital i p2 = be the proportion of patients at Hospital 2 p3 = be the proportion of patients at Hospital3
2. 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 15

Category 1 Category 2 Category 3 Failures 54 57 45 Successes 77 36 66 State the hypotheses. Choose the correct answer below. A. Ho: P1 = P2 = P3 H,: At least one of the proportions is different from the others. O B. Ho: The categories of the variable and success and failure are independent. H: The categories of the variable and success and failure are dependent. C. Ho: The categories of the variable and success and failure are dependent. H4: The categories of the variable and success and failure are independent. O D. Ho: H1 =E1 H2 = E2 and µ3 = E3 H1: At least one mean is different from what is expected. and %3D What is the P-value? (Round to three decimal places as needed.) What conclusion can be made? O A. The P-value is less than a, so do not reject Ho. There is not sufficient evidence…
