An article reports the following values for soil heat flux of eight plots covered with coal dust.
37.0 32.7
37.0 37.3 35.2 28.5
18.8 24.2
n USE SALT
The mean soil heat flux for plots covered only with grass is 29.0. Assuming that the heat-flux distribution is approximately normal, does the data suggest that the coal dust is effective in increasing the mean heat
flux over that for grass? Test the appropriate hypotheses using a = 0.05.
State the appropriate hypotheses.
O Ho: µ = 29
H:µ < 29
|O Ho: µ # 29
Ha: µ = 29
Ο H: μ= 29
Ha: H > 29
Ο H: μ 29
Ha: u + 29
Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places and your P-value to three decimal places.)
