From a sample of 25 samples, the company finds a sample mean of 13,000 Hours. At 0.05 significance level, should the company conclude that the average life of the gadget is less than the hypothesized 14,500 Hours? Construct proper hypothesis and test it with using z test.

| 14. | In a survey a random sample of 198 farms were classified into three classes according to tenure status as owned, rented and mixed. They were classified according to the level of the soil fertility as highly fertile, moderately fertile and low fertile farms. The results are given below:
Classification of farms by tenure status and fertility level.
Hypothesis HO – The tenure status doesn’t depend on soil fertility. H1 – The tenure status depends on soil fertility. Compute Chi-Square Test and take decision on the above hypothesis. Significant level at the 5%. The critical value x2 is 9.488. |

An experiment was conducted to study the effect of four levels of nitrogen on yield of paddy. The four levels of nitrogen were classified:
Table showing the yields of grain (in Kg per plot)
State the H0 and H1 and determine the observe F value. Compare it to the critical F value and make a decision whether to reject the null hypothesis. Calculate Analysis of variance (ANOVA). Table value of F at 1 percent level of significance is 5.29. |
