Question
The main point in one-sample hypothesis testing is to determine The sample size necessary to estimate the population If there is more than one sample If the sample is taken from the population If one sample is large enough to estimate the population value If you have a sample size larger than 100, and a known standard deviation of the population (sigma), you would use the to test for significance. Z distribution for one-sample proportions t distribution for one-sample proportions t distribution for one-sample proportions Z distribution for one-sample means If you have a sample size smaller than 100, and an unknown standard deviation of the population (sigma), you would use the to test for significance. t distribution for one-sample means Z distribution for one-sample proportions t distribution for one-sampleExplanation / Answer
32) C . One sample t test is used to check if sample is taken from Population
33) D If number of obs ,here 100, is more than 30 then go for Z dist. Also, its a test of sample from a population.
34) A If population std dev not known and sample is small use T test
