Answer)
As the sample size is smaller than 30
We will use t distribution table to estimate the critical value
Degrees of freedom = n-1 = 15
For 15 dof and 0.05 alpha
Critical value t from t table is = 1.753

find the critical value associated with a right sided hypothesis of the mean using a sample of size n=16 at 5% signifgnace
Using either the critical value rule or the p-value rule, if a one-sided null hypothesis for a single mean cannot be rejected at a given significance level, then the corresponding two-sided null hypothesis (i.e., the same sample size, the same standard deviation, and the same mean) will ______________ be rejected at the same significance level. always sometimes never
(a) Determine the critical value(s) for a right-tailed test of a population mean at the α=0.05 level of significance with 10 degrees of freedom. (b) Determine the critical value(s) for a left-tailed test of a population mean at the alphaαequals=0.01level of significance based on a sample size of n=20. (c) Determine the critical value(s) for a two-tailed test of a population mean at the α =0.10 level of significance based on a sample size of n=16.
1) Find the chi-square critical value for a right-tailed hypothesis test about variance at the 1% significance level with a sample size of 15
(1 point) Find the critical value if you are conducting a x2-right test based on a simple random sample of size 16, and using a significance level Q=0.05. The critical value is | Hint: Use Chart A4 of the 2-distribution at page 727.
Find the critical value(s) for a right-tailed test for a population variance, sample size n = 12, and level of significance α-o025. The critical value(s) is(are) (Use a comma to separate answers as needed. Round to three decimal places as needed.)
1. Using the traditional hypothesis testing approach, calculate the critical value for testing the null hypothesis that the population mean is greater than or equal to 12, given a sample size of 49, a population standard deviation 6.06, and a significance level of 0.05. Round to two decimals. K = 2.
