I AM RESUBMITTING THIS QUESTION FOR DIFFERENT PARTS. I AM AT THE SECOND NUMBER 2 QUESTION "P-VALUE =". Before the furniture store began its ad campaign, it averaged 160 customers per day. The manager is investigating if the average has changed since the ad came out. The data for the 16 randomly selected days since the ad campaign began is shown below: 131, 127, 148, 143, 141, 153, 158, 145, 138, 163, 164, 148, 166, 154, 170, 133 Assuming that the distribution is normal, what can be concluded at the αα = 0.05 level of significance? For this study, we should use Select an answer t-test for a population mean z-test for a population proportion The null and alternative hypotheses would be: H0:H0: ? μ p Select an answer < = ≠ > H1:H1: ? p μ Select an answer = > ≠ < The test statistic ? t z = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.) The p-value is ? ≤ > αα Based on this, we…
Suppose the mean height in inches of all 9th grade students at one high school is estimated. The population standard deviation is $5$ inches. The heights of $9$ randomly selected students are $69$, $ 63$, $ 65$, $ 68$, $ 70$, $ 62$, $ 68$, $ 69$ and $64$. $ \bar{x} $ = Margin of error at $95\%$ confidence level = $95\%$ confidence interval = [smaller value, larger value]
Slove the Following: #1. If n=490 and ˆpp^ (p-hat) =0.46, find the margin of error at a 99% confidence level. Give your answer to three decimals #2. In a recent poll, 340 people were asked if they liked dogs, and 31% said they did. Find the margin of error of this poll, at the 95% confidence level. Give your answer to three decimals #3. If n = 540 and ˆpp^ (p-hat) = 0.7, construct a 99% confidence interval.Give your answers to three decimals. #4. Out of 300 people sampled, 279 had kids. Based on this, construct a 90% confidence interval for the true population proportion of people with kids. Give your answers as decimals, to three places. #5. A political candidate has asked you to conduct a poll to determine what percentage of people support her.If the candidate only wants a 4% margin of error at a 95% confidence level, what size of sample is needed? Give your answer in whole people. #6. Assume that a sample is used to estimate a population proportion p. Find the 90%…
If Tayesha's dad hires her a tutor in statistics so that she will score in the top 20% of the class for Exam 1, what is the minimum that Tayesha's score (X) on the exam could be? The mean of the class was 82 with a standard deviation of 6. -> YOUR ANSWER SHOULD BE TO THE NEAREST HUNDREDTH.
Can you help me with the code for how to do this in R please? 1. The study "Digital Footprints" ([Pew Internet and American Life Project]("Digital Footprints" (Pew Internet and American Life Project)) reported that 47\% of Internet users have searched for information about themselves online. The 47\% figure was based on a random sample of Internet users. Suppose that the sample size was `n = 400`. i) Use this information to estimate the true proportion of Internet users who searched information about themselves using a default 95\% confidence interval. ii) Repeat (i) but instead use a 98\% Confidence Level. Use function `prop.test()`. iii) What is the main difference between the intervals computed in (i) and (ii)? What do you think is the role of the confidence level in determining the precision of the confidence interval estimate?
Suppose X ~ N (2, 3). What value of x has a z-score of -0.69? Suppose X ~ N(4, 2). What value of x is two standard deviations to the right of the mean? I need help solving these two problems. If you could explain that would help understand the steps of solving these types of problems. Thank you for your time
For this problem, carry at least four digits after the decimal in your calculations. Answers may vary slightly due to rounding. What percentage of your campus student body is female? Let p be the proportion of women students on your campus. (a) If no preliminary study is made to estimate p, how large a sample is needed to be 99% sure that a point estimate p^ will be within a distance of 0.07 from p? (Round your answer up to the nearest whole number.) | students (b) A report indicates that approximately 60% of college students are females. Answer part (a) using this estimate for p. (Round your answer up to the nearest whole number.) students
Suppose the scores of students on an exam are normally distributed with a mean of 376 and a standard deviation of 30. Then approximately 95% of the exam scores lie between the integers _ & _ such that the mean is half way between these two integers. I know the answers are 316 and 436. But I don't know how they got them. I cannot use excel and so I need help to solve this by hand. Thanks so much in advance!

The distribution of IQ scores of the population is normally distributed with a mean of 100 and a standard deviation of 15 for a particular data value. Since the population is normally distributed all sampling distributions will also be normally distributed. Find the z-scores for each of the following. Make sure to pay attention to the distribution you should use. Write exact answers as decimals. A single person with an IQ of 121: Z-score = Mean of a sample of 4 IQ's is 121: Z-score = 2.80 Mean of a sample of 9 IQ's is 121: Z-score = 1.40 Mean of a sample of 25 IQ's is 121: Z-score = 4.20 Mean of a sample of 100 IQ's is 121: Z-score = Mean of a sample of 625 IQ's is 121: Z-score = 7.00 14.00 35.00
