Hei!
Jeg står helt bom fast, og får ikke til to oppgaver. kan noen hjelpe meg?
1. Given the following ANOVA table:
Source DF SS MS F
Regression 1 1,050 1,050.00 26.00
Error 13 525 40.38
Total 14 1,575
(a) Determine the coefficient of determination.(Round your answer to 2 decimal places.)
Coefficient of determination
(b)
Assuming a direct relationship between the variables, what is the correlation coefficient? (Round your answer to 2 decimal places.)
Coefficient of correlation
(c) Determine the standard error of estimate. (Round your answer to 2 decimal places.)
Standard error of estimate
Oppgave 2:
The null and alternate hypotheses are:
H0 : μ1 = μ2
H1 : μ1 ≠ μ2
A random sample of 8 observations from one population revealed a sample mean of 21 and a sample deviation of 4. A random sample of 10 observations from another population revealed a sample mean of 23 and a sample standard deviation of 4.5.
At the .05 significance level, is there a difference between the population means?
(a)
State the decision rule. (Negative amounts should be indicated by a minus sign. Round your answer to 3 decimal places.)
The decision rule is to reject H0 if t < or t > .
(b) Compute the pooled estimate of the population variance. (Round your answer to 3 decimal places.)
Pooled estimate of the population variance
(c)
Compute the test statistic. (Negative amount should be indicated by a minus sign. Round your answer to 3 decimal places.)
Test statistic
(d) State your decision about the null hypothesis.
Håper noen flinke sjeler der ute kan hjelpe meg!!
mvh

Du burde i det minste fylle ut med det du har oppnådd så langt. Det er ikke veldig vanlig at andre pløyer leksa di 
Her ser det også ut som om det er noe som mangler. Har du copy-pasta fra en pdf, så er det vanlig at enkelte tegn går tapt.håpløsjente91 wrote: The decision rule is to reject H0 if t < or t > .
