n an independent samples t-test, the researcher is drawing a bar plot for their data and they want to include SE (Standard Error) Error bars. They have an experimental condition (Mean = 5, SE = 1) and a control condition (Mean = 3, SE = 1). The error bars for the experimental condition bar will extend from ______ to _____

If we want to estimate the probabilities of this graph, we should use Chebyshev's Theorem + 2. How much of the data can we estimate to be between x-values -15 and 105? Round to the nearest tenth. There is at least 68 x % of the data is between -15 and 105. 3. How much data is between 2 standard deviations of the mean? There is at least 95 x % of the data between 2 standard deviation of the mean.

IQ tests supposedly measure our intelligence. They typically are ‘normed’ so that they have a mean of 100 and a standard deviation of 15. (Higher scores show higher intelligence.) Use the graph and use the z-score and percents from columns b and c in Table A, when relevant. If you scored 132, what is your z-score? (Interpret.) Use table A X, z(a), (b), and (c) X z (a) (b) (c) and use the graph! Write down or save your response to use in Part 2 of this quiz. Group of answer choices -2.53 z.
