2 What is the critical value for a test of significance in the following? (Use table A or B on the back cover). One-tailed test alpha=0.05 standard deviation is unknown n=10.3 Given Ho: m=45 Ha: m<45 alpha=0.05 n=16 standard deviation is unknown and test statistic=-1.703. After finding the critical value you would reject the null hypothesis. T or F4 In the previous question is there a possibility of a type I error? How about the probability of type II error? Explain5 The mean of weight of 46 individuals is 75kg with a population standard deviation of 8.4. What is the 95% confidence interval for the mean?6 For 100 individuals the sample diastolic blood pressure is 73 mmHg with the standard deviation s = 11.6 mmHg. Construct a two-side 95% confidence interval for the mean.
