Transcribed Image Text:A magazine tested LCD televisions. The table below shows the overall quality score and cost in hundreds of dollars. Use the rank correlation coefficient to test for a correlation between the two
variables. Use a significance level of a = 0.05. Based on these results, can you expect to get higher quality by purchasing a more expensive LCD television?
Quality 78 74 71 69 65
Cost
27 28 37 23 20
Determine the null and alternative hypotheses for this test. Choose the correct answer below.
O A. Ho: Ps #0
H₁: Ps = 0
O C. Ho: rs #0
H₁: r₂ = 0
64 61 60 60 59 58
15 27 23 16 15 20
Determine the correlation coefficient.
Ts= (Round to three decimal places as needed.)
Determine the critical value(s) of the correlation coefficient.
OB. Ho: Ps = 0
H₁: Ps #0
O D. Ho: rs = 0
