Calculate the critical t value s for each of the given hypothesis test scenarios below If multiple critical values exist for a single scenario enter the solutions using a comma separated list Round t values to four decimal places Find the critical t value s for a left tailed test of hypothesis for a mean assuming the population standard deviation is unknown with a sample size of 11 and a significance level of 0 5 t Find the critical t value s for a right tailed test of hypothesis for a mean assuming the population standard deviation is unknown with a sample size of 68 and let a 0 1 t Find the critical t value s for a two tailed test of hypothesis for a mean assuming the population standard deviation is unknown with a sample size of 52 and let a 0 01 t Find the critical t value s for a two tailed test of hypothesis for a mean assuming the population standard deviation is unknown with a sample size of 60 and a significance level of 2
