I'm having trouble with this. Please show work so I can see where I'm messing up. Thanks 1. For each sample, state the sample size, mean, and standard deviation. Sample A: 0.75, 1.38, 2.13, 2.45, 4.7 Sample B: 2.18, 3.5, 4.7, 5.63, 7.35 2. State Hypotheses in statistical format: a. H0: b. H1: 3. State Significance Level: Use significance level α = .05 4. State critical t (explain how it was found) 5. State decision rule 6. Calculate the test...
Recall that the formula for a confidence interval is Statistc + MOE. Next you will need to interpret the confidence interval. The interpretation of a confidence interval should always include 3 things: the level of confidence, reference to the parameter in context and the calculated interval. Notice that the only difference between this worksheet and the calculating confidence intervals worksheet from module 8 is that you now need to calculate the margin of error. 1. Suppose that a recent study...
Hi there, I just need help with the last couple sub parts of this question. I'm having a difficult time understanding this. Can somebody help me please? Below is the data for a personality questionnaire measuring conscientiousness. These data were taken from a random sample of 16 undergraduate psychology majors. In the general population, scores on this questionnaire are normally distributed with a mean (μ) of 50. You hypothesize that this sample is not representative of the general population. Specifically,...
I recommend that you practice using the standard Normal tables to calculate zα/2 and tα/2 . Costs are rising for all kinds of health care. The mean monthly rent at assisted-living facilities was recently reported to have increased 15% over the last five years. A recent random sample of 120 observations reported a sample mean of $3563. Assume that past studies have informed us that the population standard deviation is $650. For this problem, round your answers to 2 digits...

"I'll never understand this accounting stuff, Blake Dunn yelled, waving the income statement he had just received from his accountant in the morning mail. "Last month, we sold 2,000 stuffed State University mascots and earned $6,565 in operating income. This month, when we sold 3,000 I thought we'd make $9,848. But this income statement shows an operating income of $11,615! How can I ever make plans if I can't predict my income? I'm going to give Janice one last chance...
