दा (c) Draw a t-distribution that depicts the critical region. (d) Will the researcher reject the null hypothesis? Why? gnific n tha' 6. To test Ho: u = 80 versus H;: µ < 80, a simple random sample of size n = 22 is obtained from a population that is known to be normally distributed. (a) If x = 76.9 and s = 8.5, compute the test statistic. (b) If the researcher decides to test this hypothesis at the a = 0.02 level of significance, determine the critical value. ample o be %3D %3D de.
Permutations and Combinations
If there are 5 dishes, they can be relished in any order at a time. In permutation, it should be in a particular order. In combination, the order does not matter. Take 3 letters a, b, and c. The possible ways of pairing any two letters are ab, bc, ac, ba, cb and ca. It is in a particular order. So, this can be called the permutation of a, b, and c. But if the order does not matter then ab is the same as ba. Similarly, bc is the same as cb and ac is the same as ca. Here the list has ab, bc, and ac alone. This can be called the combination of a, b, and c.
Counting Theory
The fundamental counting principle is a rule that is used to count the total number of possible outcomes in a given situation.
