b) What do you understand by the reliability and validity of a measuring procedure?
c) List and describe in brief five exs of scientific misconduct.
d) prepare down the major differences between the qualitative and quantitative research.
problem 2: A normal distribution is thought to have a mean of 50. A random sample of 100 gave a mean of 52.6 and a standard deviation of 14.5. A significance test was carried out at the 5% level to validate an increase in the population mean.
By letting the population mean to be µ and population variance to be σ2
a) Formulate the hypothesis for the problem.
b) Compute a 95% confidence interval for µ.
By using the standard test statistic the null hypothesis is discarded at the 5% level of confidence.
c) Describe what is meant here, paying particular attention to the level of the significance?
d) What would be your conclusion at the 10% level of importance?
a) Go through the research paper provided.

- prepare down the major findings of the research.
- Recognize all the components of the last reference (that is, made to D Wilks) in the paper. Why a specific reference to the page number is missing here?
