- Here is a bivariate data set.xy182425915011737106295223812246 Find the correlation coefficient and report it accurate to four decimal places. r =Two samples of sizes 60 and 90 have 52 and 48 as the respective A.Ms. and 9 and 12 as the respective S.Ds. Find the A.M and S.D. of the combined sample of size 150.What size samples do you need for a 2-group design if you expect to have an effect size of .50 and you want your power to be .71?
- A researcher collects data that represents the average number of hours of sleep in the last two nights by 8 depressed patients and 9 non-depressed patients. The researcher is interested in whether the two groups reliably differ in the amount of sleep they get. Use Jamovi to calculate t-obt and the p value.Denise runs a dependent samples t-test and calculates r2subjects=.46 and r2condition=.23. a) SScondition is what proportion of SSsubjects (give in 2 decimals)?"given a simple regression with slope b=3, s (sub y)=8, and s (sub x)= 2, and n=30. Find the standard error of the estimate."
- If X is b(100,0.1), how do you find the value of P(12 < X < 14) using the normal approximation and the Poisson approximationWe want to estimate the causal effect of D through regression, and S allows a perfect stratification. There are N stratums in S and we use Si to represent stratum i. If the estimated coefficient of Si*D is A and is significant, then the treatment effect of D for stratum i is A.For an alpha = .10 and degrees of freedom, df = 32, what is the one-tailed t-value? Give your answer exactly as it appears in the table, with three decimal places.

However, a researcher believes the relationship is stronger for children. The researcher tests a sample of 28 children and obtains an rxy = .47. Does this result support the researcher’s belief? Conduct an appropriate statistical test using an alpha level of .05.
