T/F Question and explain

1.A 95% confidence interval for population mean μ is 65.6±12.8 from a sample of size n=96. If one took a second random sample of the same size, then the probability that the 95% confidence interval for μ based on the second sample contains 65.6 is 0.95.

2.The probability of a Type I error when α=0.05 and the null hypothesis is true is 0.05.

3.Because an assumption of ANOVA is that all of the population variances are equal, inferences will be unreliable unless the sample standard deviations are all equal up to two significant digits.
