A farmer in Kota Sarang Semut, Kedah, uses a lot of fertilizer to grow his crops. The farmer's manager thinks fertilizer products from distributor A contain more of the nitrogen that his plants need than distributor B's fertilizer does, He takes two Independent samples of 5 batches of fertilizer (n=n>=5) from each distributor and measures the amount of nitrogen in each batch. Fertilizer from distributor A contained 10 kg per batch and fertilizer from distributor B contained 8 kg per batch. Suppose the population standard deviation for distributor A and distributor B is 2 kg per batch and 3 kg per batch, respectively. Assume the distribution of nitrogen in fertilizer is normally distributed. Let u, and we represent the average amount of nitrogen per batch for fertilizer's A and B, respectively. The competing hypotheses to determine if fertilizer A contains more nitrogen per batch than fertilizer B is given below:Which of the following is an appropriate p-value? A. 0. 0228 B. 0. 0455 C. 0. 1075 D. 0.2146Which of the following is the correct value of the test statistic? A. to = 1.24 B, to = 2 C. z = 1.24 D. Z = 2Which of the following is the appropriate conclusion at the 5% significance level? A. Reject Ho; we can conclude that the mean amount of fertilizer per batch for distributor A is greater than the amount of fertilizer per batch for distributor B. B. Reject Ho; we cannot conclude that the mean amount of fertilizer per batch for distributor A is greater than the amount of fertilizer per batch for distributor B. C. Fail to reject Haj we can conclude that the mean amount of fertilizer per batch for distributor A is greater than the amount of fertilizer per batch for distributor B. D. Fail to reject Ho; we cannot conclude that the mean amount of fertilizer per batch for distributor A is greater than the amount of fertilizer per batch for distributor B
