## Sample MA8452 Question Bank Statistics and Numerical Methods:

1. Define Type-I error and Type-II error? BTL -1 Remembering

2. Mention the various steps involved in testing of hypothesis BTL -1 Remembering

3. What are null and alternate hypothesis? BTL -1 Remembering

4. What is the essential difference between confidence limits and
tolerance limits? BTL -1 Remembering MA8452 Question Bank Statistics and Numerical Methods

5. What are the parameters and statistics in sampling BTL -1 Remembering

6. State level of significance. BTL -1 Remembering

7. Twenty people were attacked by a disease and only 18 were
survived. The hypothesis is set in such a way that the survival
rate is 85% if attacked by this disease. Will you reject the
hypothesis that it is more at 5% level.(????????.???????? = ????. ????????????)
BTL -2 Understanding MA8452 Question Bank Statistics and Numerical Methods

8. A random sample of 25 cups from a certain coffee dispensing
machine yields a mean x = 6.9 occurs per cup. Use 0.05 level of
significance to test, on the average, the machine dispense μ = 7.0
ounces against the null hypothesis that, on the average, the
machine dispenses μ < 7.0 ounces. Assume that the distribution
of ounces per cup is normal, and that the variance is the known
quantity ????2=0.01 ounces.

9. In a large city A, 20 percent of a random sample of 900 school
boys had a slight physical defect. In another large city B, 18.5
percent of a random sample of 1600 school boys had some
defect. Is the difference between the proportions significant?

10. A standard sample of 200 tins of coconut oil gave an average
weight of 4.95 kg with a standard deviation of 0.21 kg. Do we
accept that the net weight is 5 kg per tin at 5% level of
significance? MA8452 Question Bank Statistics and Numerical Methods
