6. What type of car is more popular among University students, South African orforeign? One hundred fifty-nine college students were randomly sampled and eachI was asked which type of car he or she prefers. A computer package was used togenerate the printout below for the proportion of college students who preferAmerican automobiles.SAMPLE PROPORTION=SAMPLE SIZEUPPER LIMITLOWER LIMIT==0.3962261590.464920.331153Is the sample large enough for the interval to be valid?(a) Yes, since n > 30.(b) No, the population of college students is not normally distributed.(c) Yes, since np and nâ are both greater than 15.(d) No, the sample size should be at 5% of the population.

Aresearcher wishes to estimate the percentage of adults who support abolishing the penny. What size sample should be obtained if he wishes the estimate to be within 3 percentage points with 95% confidence if (a) he uses a previous estimate of 22% (b) he does not use any prior estimates? (Round up to the nearest integer.) (a) n (b) n Round up to the nearest integer.)
11th -The variance of the sample formed by the sample averages of the samples randomly taken from a population with the condition of substitution, with a size of n=100, was found to be 0.01. What is the sample standard error value?a)0.001 B)0.014 NS)0.20 D)0.032 TO)0.10
Is it possible for the 50th percentile of a distribution to be equal to the 60th percentile? Why or why not? A. No, because you won’t get the same result multiplying by 50 as you do by 60. B. No, because there will always be some values of the distribution in between the 50th and 60th percentiles. C. Yes, this can happen if the distribution is uniform. D. Yes, this can happen if there are many members of the population with the same value.
2) In the year 2033, Kayla Faruq is leading emergency room doctor. Kayla is presently researching the relationship between stress and cardiovascular disease. Suppose systolic blood pressures of patients that are experiencing chronic stress is normally distributed with a mean of 140 and a standard deviation of 5.9.
The first pic is the question. Since some tutors have been solving the problems wrong recently (no judgment), I’ve added a sample question to solve problem.
52. Multiple Choice If the calorie contents of robin eggs are normally distributed with a mean of 25 and a standard devia- tion of 1.2, then approximately 95% of all robin eggs should In have a calorie content in the interval ex (A) [21.4, 28.6]. (B) [22, 28]. (C) [22.6, 27.4]. (D) [23, 27]. (E) [23.8, 26.2].
A coin was flipped 69 times and came up heads 39 times. At the .10 level of significance, is the coin biased toward heads? (a-1) H0: ππ ≤ .50 versus H1: ππ > .50. Choose the appropriate decision rule at the .10 level of significance. Reject H0 if z > 1.282 Reject H0 if z < 1.282 a b (a-2) Calculate the test statistic. (Carry out all intermediate calculations to at least 4 decimal places. Round your answer to 3 decimal places.) Test statistic (a-3) The null hypothesis should be rejected. False True (a-4) The true proportion is greater than .50. False True (b-1) Find the p-value. (Round your answer to 4 decimal places.) p-value (b-2) Is the coin biased toward heads? No Yes
Mo. Please give only typed answer.
The random variable x has a normal distribution with mean 50 and variance 9. Find the value of x, call it x0, such that: a) P(x ≤ xo) = 0.8413 b) P(x > xo) = 0.025 c) P(x > xo) = 0.95 d) P(41 ≤ x ≤ xo) = 0.8630
The average age of managers in a particular industry is over 35 years old, and we wishe to prove this. The null hypothesis to conduct a statistical test on this theory would be: the population mean is ˃ 35, or the population mean is ≤ 35 or the population mean = 35 or the population mean is ≥ 35.
I'm not sure how to solve for (b)at least 6 where P(x is less than or equal to 6) or (c)less than 4 where P(x is less than 4). I was able to follow the sample problem in my text to solve (a) exactly 5, but I'm confused on how to apply it to part (b) and (c).
