Which of the following statements is true? The t-distribution with 1 degree of freedom is equivalent to the standard normal distribution. When division by a factor of n-1 is used, the sample variance s2 is an unbiased estimator of the population variance σ2. If a hypothesis test is conducted at the 5% significance level, then a p-value of 0.087 would lead the researcher to reject H0. A 99% z-based confidence interval of the population mean μ based on a sample...
