Answer #1

The null hypothesis states that there is no any difference between the variables being compared or that any difference that does exist can be explained by chance. The alternative hypothesis defined as observed difference is not likely to have occurred by chance alone but likely to be genuine.
Null Hypothesis: The increase in robberies has NOT been driven by an increase in gold jewellery thefts, particularly in Asian neighbourhoods
Alternative Hypothesis: The increase in robberies has been driven by an increase in gold jewellery thefts, particularly in Asian neighbourhoods
Directional Hypothesis: The number of killings by thiefs are lower than contract killers.

For each of the following studies, state both the null and alternative hypotheses and the decision rule, then work the problem. Look up the critical value of t that would cut off the tails of the distribution. Note that each study specifies the alpha value to use and whether to use a one- or two-tailed test. Decide whether to reject or fail to reject the null and answer the question. The first example does not include a sample size, I...
