A random sample of soil specimens was obtained, and the amount of organic matter (%) in the soil was determined for each specimen, resulting in the accompanying data. 1.10 5.09 1.20 3.50 0.69 4.47 0.97 1.59 4.60 5.02 4.67 5.22 3.31 1.17 0.76 0.32 0.55 1.45 0.14 4.47 2.69 3.98 3.17 3.03 2.21 1.17 1.57 2.62 1.66 2.05 The values of the sample mean and sample standard deviation are 2.481 and 1.616, respectively. Suppose we know the population distribution is normal, does this data suggest that the true average percentage of organic matter in such soil is something other than 3%? Carry out a test of the appropriate hypotheses at significance level 0.10 using the P-value method.
