- CAn you fill out whats blankMore Information From the Online Dating Survey A survey conducted in July 2015 asked a random sample of American adults whether they had ever used online dating (either an online dating site or a dating app on their cell phone). 18-to 24-year-olds The survey included 194 young adults (ages 18 to 24) and 53 of them said that they had used online dating. If we use this sample to estimate the proportion of all young adults to use online dating, the standard error is 0.032. Find a 90% confidence interval for the proportion of all US adults ages 18 to 24 to use online dating. Round your answers to three decimal places.

- Question : i do not understand how to compute this problem. Are teachers evaluations independent of grades? After midterms, a random sample of 284 students was asked to evaluate teacher performance. The students were also asked to supply their midterm grade in the course being evaluated. In this study, only students with a grade of A, B, or C were included in the summary table. Use a 5% level of significance to test the claim that teachers evaluations are independent of midterm grades. Mid Term Grade Evaluation A B C Row Total Positive 53 33 18 104 Neutral 25 46 29 100 Negative 14 22 44 80 Column Total 92 101 91 284Hi Can you answer the wrong problemsIf an ANOVA test is conducted and the null hypothesis is rejected, what does this indicate?

- Analysis of variance compares the means of a response variable for several groups. ANOVA compares the variation within each group to the variation of the mean of each group. The ratio of these two is the F statistic from an F distribution with (number of groups - 1) as the numerator degrees of freedom and (number of observations - number of groups) as the denominator degrees of freedom. You intend to conduct an ANOVA with 4 groups in which each group will have the same number of subjects: n=20. (This is referred to as a "balanced" single-factor ANOVA.)

O The analysis of variance, or more briefly ANOVA, refers broadly to a collection of experimental situations and statistical procedures for the analysis of qu experimental units. The simplest ANOVA problem is referred to as two-way ANOVA. Single-factor ANOVA focuses on a comparison of more than two population or treatment. All of the above statements are true. None of the above statements are true.
