You are conducting a t-test to assess the null hypothesis H0: μ = 50 against the two-sided alternative. You collect a random sample of n=25 observations. The sample has a mean of 55 and a standard deviation of 10. How many degrees of freedom does the test have? Assume the underlying distribution is normal.
(a) Supposen - 6 and the sample correlation coefficient is r=0.884. Is significant at the 1% level of significance (based on a two-tailed test)? (Round your answers to three decimal places) critical Condusion: Yes, the correlation coefficient p is significantly different from 0 at the 0.01 level of significance No, the correlation coefficient is not significantly different from 0 at the 0.01 level of significance (b) Supposen - 10 and the sample correlation coefficient is 0.884. Isr significant at the...

3. A hospital administrator wished to study the relation between patient satisfaction (Y) and patients age (Xi, in years), severity of illness (X2, an index) and anxiety level (X3, an index). The administrator randomly selected 23 patients and collected the data in pat, where larger values of Y, X2 and X3 are, respectively, associated with more satisfaction, increased severity of illness and more anxiety. The data is saved in Moodle2...
