Answer: t= 2.032
Step-by-step explanation:
Given : Sample size :
Sample mean :
Standard deviation :
Claim : The IQ scores of statistics professors are normally distributed, with a mean greater than 116.
Let be the mean scores of statistics professors.
Then the set of hypothesis for the given situation will be :-
As the alternative hypothesis is right tailed , thus the test would be right tail test.
Since the sample size is less than 30, therefore the test would be t-test .
The test statistics for the given situation will be :-
Hence, the value of the test statistic : t= 2.032
Answer:
Option C
Step-by-step explanation:
The first number is - 3, then we have a blank and the third number is - 1 1/8
In order for the numbers to be arranged from least to greatest, the number in the center should be greater than -3, and lesser than -1 1/8
Note that for negative numbers, the larger the constant, the smaller the number. i.e. -5 is smaller than -4.
So from the given options, the only number that is greater than -3 and lesser than -1 1/8 is - 2 1/4
So, option C gives us the correct answer to have the numbers ordered from least to greatest.
