See Answer →A manufacturer wishes to determine the effectiveness of four types of machines (A, B, C and D) in the production of bolts. To accumulate this, the numbers of defective bolts produced for each of two shifts in the results are shown in the following table:
| Machine | First Shift | Second Shift | ||||||||
| A | 6 | 4 | 5 | 5 | 4 | 5 | 7 | 4 | 6 | 8 |
| B | 10 | 8 | 7 | 7 | 9 | 7 | 9 | 12 | 8 | 8 |
| C | 7 | 5 | 6 | 5 | 9 | 9 | 7 | 5 | 4 | 6 |
| D | 8 | 4 | 6 | 5 | 5 | 5 | 7 | 9 | 7 | 10 |
Perform an analysis of variance to determine at 5% level of significance, whether there is a difference (a) Between the machines and (b) Between the shifts.

Find the number of samples using Proportional and Neyman allocation techniques and compare. Obtain the sample mean and variances for the Proportional Allocation and SRSWOR for the given information. Then Find the percentage gain in precision of variances of sample mean under the proportional allocation over that of SRSWOR.

An experiment was planned to study the effect of Sulphate, Potash and Super Phosphate on the yield of potatoes. All the combinations of 2 levels of Super Phosphate [0 cen and 5 cent
acre] and two levels of Sulphate and Potash [0 cen
and 5 cent
acre] were studied in a randomised block design with 4 replications each. The (1/70) yields [lb per plot = (1/70) acre] obtained are given in table below:
| Blocks | Yields | |||
| I | (1) 23 | k 25 | p 22 | kp 38 |
| II | p 40 | (1) 26 | k 36 | kp 38 |
| III | (1) 29 | k 20` | pk 30 | p 20 |
| IV | kp 34 | k 31 | p 24 | (1) 28 |
Analyse the data and give your conclusions.
See Answer →Three varieties A, B and C of wheat are shown in five plots each of the following fields per acre as obtained:
| Plots | A | B | C |
| 1 | 8 | 7 | 12 |

| 3 | 7 | 10 | 13 |
| 4 | 14 | 9 | 12 |
| 5 | 11 | 9 | 14 |
