Two statistical methods are being considered for decreasing the number of defectives in a production line. Samples are taken under both methods. The results are summarized below. \begin{tabular}(|1|0|0} Vhline & Sample size & Number of defectives Thline Method 1 & 5000 & 100 W Thline Method 2 & 4000 & 40 \hline \end{tabular Test whether there is sufficient evidence to conclude that method 2 has decreased the proportion of defects by more 1 percent than method 1 Show area of p-value and calculate it. Use $0.1$ level of significance. SP.SD.059
