Just from $13/Page germination rate. Before the farming cooperative will buy from this seed merchant, they want to verify this claim. A random sample of 320 wheat seeds supplied by this seed merchant was tested, and it was found that only 230 seeds germinated. Is there sufficient statistical evidence at the 3% significance level to justify the purchase of wheat seeds from this seed merchant? Use the p-value approach to conduct a hypothesis test for a single proportion, and report the findings to the KwaMashu farming cooperative. (10) The following null and alternative hypotheses for the population proportion needs to be tested: “H_0:p\geq0.8” “H_1:p<0.8” This corresponds to a left-tailed test, for which a z-test for one population proportion will be used. Based on the information provided, the significance level is “\alpha=0.03,” and the critical value for a left-tailed test is “z_c=-1.8808.” The rejection region for this left-tailed test is “R=\{z:z<-1.8808\}.” The z-statistic is computed as follows: “z=\dfrac{\hat{p}-p_0}{\sqrt{\dfrac{p_0(1-p_0)}{n}}}=\dfrac{\dfrac{230}{320}-0.8}{\sqrt{\dfrac{0.8(1-0.8)}{320}}}=-3.6336” Using the P-value approach: The p-value is “p=P(Z<-36336)\approx0.000140,” and since “p=0.000140<0.03=\alpha,” it is concluded that the null hypothesis is rejected. Therefore, there is enough evidence to claim that the population proportion “p” is less than 0.8, at the “\alpha=0.03” significance level. # What Will You Get?
