Given a sample size of n=45, what is the degree of freedom for hypothesis testing and confidence intervals for mean
Given a sample mean of 5.1, sample deviation of 0.75 and a sample size of 21, assuming the data is normally distributed, give the upper limit on a 95% confidence interval.
Given α=0.01 and n=19, find the critical t-score for a one-tail test of hypothesis.
1. HT Proportion: A random sample of 220 individuals who voted in the last election showed that 135 voted for the given amendment. Let be the true proportion of population of voters that voted for the given amendment. Test the claim at the 1% level of significance, that this is two-thirds majority. Determine the p-value to four decimal places.

Usually, the sample size is small (n<30), we would use the t-distribution value. However, if we know the population standard deviation, we still use the z-distribution value even though the sample size is small. Describe what the reason that we use z-distribution if we know the population standard deviation.
