Write youranswers on any clean sheet/s of paper.Strictly no solution, automaticallywrong.Teacher Rowelin wants to estimatethe average time of her students spendin TikTok and wants to calculate itusing 99% level of confidence. Shewants to know it immediately becauseof her curiosity since she haveobserved that most of them areprocrastinating. So, she randomlyselected twenty-five students tointerview and to represent all of herstudents that she handles. During theprocess, she established that therandomly selected students spend anaverage of 6hrs a day using TikTokwith standard deviation of 2hrs. Findthe length of the confidence interval.

Thompson Photo Works purchased several new, highly sophisticated processing machines. The production department needed some guidance with respect to qualifications needed by an operator. Is age a factor? Is a person's mechanical aptitude score important? To evaluate the factors needed to estimate performance on the new processing machines, four variables were selected: x1 = Length of time an employee was in the industryx2 = Mechanical aptitude test scorex3 = Prior on-the-job ratingx4 = Age Performance on the new machine is designated y.Thirty employees were randomly selected and data were collected for each of the variables. A few results follow: Name Performance on New Machine,y Length of Time in Industry,x1 Mechanical Aptitude Score,x2 Prior On-the-Job Performance,x3 Age,x4 Mike Miraglia 112 4 392 119 41 Sue Trythall 117 5 305 127 30 The equation is:yˆy⁢^⁢ = 10.3 + 0.4x1 + 0.986x2 + 0.212x3 + 0.007x4 As age increases by one year, how much does estimated performance on…
Using a TI-84 Plus calculator, I need to know the step by step process to calculate these. I don’t need these just written out on paper, but I also need to be shown the every move made into the calculator. Like, ‘STAT’ then ‘TESTS’ then ‘2: T-Test’, and so on.
To the Internal Revenue Service (IRS), the reasonableness of total itemized deductions depends on the taxpayer's adjusted gross income. Large deductions, which include charity and medical deductions, are more reasonable for taxpayers with large adjusted gross incomes. If a taxpayer claims larger th average itemized deductions for a given level of income, the chances of an IRS audit are increased. Data (in thousands of dollars) on adjusted gross income and the average or reasonable amount of itemized deductions follow. Adjusted Gross Income ($1,000s) 22 Itemized Deductions ($1,000s) 9.6 27 9.6 32 10.1 48 11.1 65 11.5 85 120 19.7 23.5 (a) Develop a scatter diagram for these data with adjusted gross income as the independent variable. 30 25 20 15 • 10 5 Itemized Deductions ($1,000s) 0 20 40 60 80 100 120 Adjusted Gross Income ($1,000s) 140 30 25 20 15 10 5.

When the measure of spread is compared between two data sets, data set A has an interquartile range of 12, and data set B has an interquartile range of 23. How do the values of data set A compare to data set B? The values of data set A are about the same on average as the values of data set B. The values of data set A are more spread out compared to the values of data set B. The values of data set A are less spread out compared to the values of data set B. The values of data set A are less on average compared to the values of data set B.
The temperature of a certain chemical process is thought to be related to the time it takes for the process to reach completion. Out goal is to that relationship so that we can use it to predict TIME TO REACH COMPLETION at various TEMPERATURES. 14 trials are set up and the time for the process to complete is measured for each of the different temperatures. The data is presented here:(data is in the image added to the question as well as more questions to answer)
Last year over 7000 students took an entrance exam at a certain state university. Kareem's score was at the 44th percentile. Lella's score was at the 93rd percentile. (a) Which of the following must be true about Kareem's and Leila's scores? Both Kareem and Leila scored higher than the median. O Both Kareem and Lella scored below than the median. O Leila scored higher than Kareem. O Kareem scored higher than Leila. (b) Which of the following must be true about Kareem's score? O About 44% of the students who took the exam scored lower than Kareem. O Kareem got about 44% of the questions correct. O Kareem's score was in the top half of all scores. O Kareem missed 56 questions. Explanation Check X 3 Ⓒ2022 McGraw Hill LLC. All Rights Reserved. Terms of Use | Privacy Center

For the items in the table below, you will have two sets of calculations to perform. First, using the split-half method, derive an estimate of reliability using the odd numbered items versus the even numbered items. You do not need to show your calculations, However, indicate the values that you obtained for (1) the sums of squares, (2) the sum of products, and (3) and the final reliability estimate as points will be allocated for those values. Second, calculate Cronbach's a. Again, you do not need to show your calculations. However, indicate the values that you obtained for (1) the variances of the items, (2) the variance of the test, and (3) the final value for Cronbach's a as points will be allocated for those values. q01 2 4 5 2 3 3 902 3 3 5 3 5 5 q03 2 4 5 3 4 4 q04 3 3 4 2 4 № st 4
A consumer group wanted to determine if there was a difference in customer perceptions about prices for a specific type of toy depending on where the toy was purchased. In the local area there are three main retailers: W-Mart, Tag, and URToy. For each retailer, the consumer group randomly selected 5 customers, and asked them to rate how expensive they thought the toy was on a 1-to-10 scale (1= not expensive, to 10 = very expensive). The toy was priced the same at all retail stores. 1. What kind of statistical test should be used to test the consumer group's research goal, assuming that the researcher wanted to use the 1-to-10 scale as a numerical interval measure? A. Repeated-measures t-test B. One-way Independent Measures ANOVA C. Repeated-measures ANOVA D. Independent-measures t-test 2. State the hypothesis that aims to test the consumer group’s research goal (i.e., what is H0 and HA).
A researcher gives a depression scale to 300 people now, 6 weeks later, and 6 months later. She finds that the depression scale means are relatively the same over those three time periods. Does this mean that the depression scale is valid, and/or reliable? Explain.
