A recent survey compared the costs of adoption through public and private agencies. For a sample of 16 adoptions through a public agency, the mean cost was $21,045, with a standard deviation of $835. For a sample of 18 adoptions through a private agency, the mean cost was $22,840, with a standard deviation of $1,545.

Question

A recent survey compared the costs of adoption through public and private agencies. For a sample of 16 adoptions through a public agency, the mean cost was $21,045, with a standard deviation of $835. For a sample of 18 adoptions through a private agency, the mean cost was $22,840, with a standard deviation of $1,545. Can we conclude the mean cost is larger for adopting children through a private agency? Use the .05 significance level

1.	Find the degrees of freedom for unequal variance test. (Round down your answer to the nearest whole number.)

2.	State the decision rule for .05 significance level: H₀: μ_c ≥ μ_r ; H₁: μ_c < μ_r. (Negative amount should be indicated by a minus sign. Round your answer to 3 decimal places.)

3.	Compute the value of the test statistic. (Negative amount should be indicated by a minus sign. Round your answer to 3 decimal places.)

4. Can we conclude the mean cost is larger for adopting children from a private agency? Use the 0.05 significance level.

(Reject/ Fail to reject) H₀. We (can/cannot) conclude the mean cost is larger for adopting children from a private agency.
