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.

Transcribed Image Text:The average fruit fly will lay 393 eggs into rotting
fruit. A biologist wants to see if the average will be
fewer for flies that have a certain gene modified.
The data below shows the number of eggs that were
laid into rotting fruit by several fruit flies that had
this gene modified. Assume that the distribution of
the population is normal.
360, 367, 373, 409, 407, 380, 382, 404, 382, 375,
405, 389, 396, 374, 401
What can be concluded at the the a = 0.01 level of
significance level of significance?
a. For this study, we should use
t-test for a population mean
b. The null and alternative hypotheses would be:
Но:
393
H1:
393
C. The test statistic t
(please show your answer to 3 decimal
places.)
d. The p-value =
(Please show your
%3D
answer to 4 decimal places.)
