Toy Assembly Test An educational researcher devised a wooden toy assembly project to test learning in 6-year-olds. The time in seconds to assemble the project was noted, and the toy was disassembled out of the child's sight. Then the child was given the task to repeat. The researcher would conclude that learning occurred if the mean of the second assembly times was less than the mean of the first assembly times. At a = 0.025, can it be concluded that learning took place? Use the P-value method. Assume that all variables are normally or approximately normally distributed. Let u₁ be the trial 1 average and p = μ₁ −μ₂. Child Trial 1 Trial 2 1 150 150 Send data to Excel 2 150 3 145 4 5 6 100 130 90 105 124 130 120 116 7 115 118

How to solve it on TI-84 Plus CE and Excel?
The website of the large coporation CorpPlus claims that 97% of the population of all employees say the corporation is a great place to work. You work for a competitor and think that this percentage is not a true indicator of CorpPlus's employee satisfaction. To test the daim from the website, you will survey a random sample of 75 employees from CorpPlus, and ask them whether they think the corporation is a great place to work. Follow the steps below to construct a 99% confidence interval for the population proportion of all employees who say the corporation is a great place to work. Then state whether the confidence interval you construct contradicts the website's daim. (If necessary, consult a list of formulas.) (a) Click on "Take Sample" to see the results from the random sample. Number Proportion Says the corporation is a great place to work Take Sample 63 0.84 Does not say the corporation is a 12 0.16 great place to work Enter the values of the sample size, the point estimate of…
Test the hypothesis using the P value approach. Be sure to verify the requirements of the test. use technology to find the P value. P value =_. (round to three decimal places as needed.)
One consumer wants to know if the average number of chips is less than 45 in a bag of Red Bird potato chips. A random sample of 100 was selected and the sample statistics werex=41.6 and s = 7.6. (i) What is the standard error of x? (ii) Using one or two sentences, briefly describe the Central Limit Theorem (CLT) for the sample mean. (ii) Does CLT hold for this test? Explain your reasoning. (iv) State the hypotheses for the test. (v) Give a 90% CI (3 d.p.) for the average amount of chips in each bag (The margin of error is 1.262). (vi) Interpret your Cl in part (iv) in context. (vii) Make a decision and conclusion based on your Cl in part (v).
We wish to estimate what percent of adult residents in a certain county are parents. Out of 200 adult residents sampled, 188 had kids. Based on this, construct a 90% confidence interval for the proportion p of adult residents who are parents in this county.Express your answer in tri-inequality form. Give your answers as decimals, to three places._____ < p < _____ Express the same answer using the point estimate and margin of error. Give your answers as decimals, to three places.p = _____ ± _____

What is a point estimate in a confidnece interval for a t test?
You would like to construct a 99% confidence interval to estimate today's population mean temperature, so you make a series of measurements (a random sample) throughout the day. The mean of these measurements is 58.5 degrees Fahrenheit, and their standard deviation is 3.0 degrees Fahrenheit. (a) What is the best point estimate, based on the sample, to use for the population mean? ( ) degrees
