<PRE><B>Question 1040120</B>
A random sample of size 15 is selected from a normal population. The population standard deviation is unknown. Assume the null hypothesis indicates a two-tailed test and the researcher decided to use the 0.10 significance level. For what values of t will the null hypothesis not be rejected? 
--------
Find the t-value with a right tail of 5% when df = 14
invT(0.95,14) = 1.7613
-------
Ans:: -1.7613 &lt; t &lt; 1.7613
