Answer:
2.51 < σ < 3.92
Step-by-step explanation:
We will use Chi-Square distribution to create the interval. We have the following information:
n = 41
Level of Confidence : 95%,
This corresponds to Chi-Square values of:
24.433 for the left tail and 59.342 for the right tail
We need to calculate the sample Variance. This is done on attached photo 1 (the shortcut formula for finding variance was used)
We get s = 9.3866.
See the construction of the confidence interval on the second attached photo
Answer:
amog us
Step-by-step explanation:
This is a negative graph because the graph go to the left with a negative slope. Y=-1/2x
When you are doing an equation like this, multiply every variable by the next. For example, if you had how many ways could 5 colors be arranged, you would do 5 times 4 times 3 times 2 times 1, because there are 5 options for space 1, 4 for space 2 and so on. For this equation, the first coin you toss has 2 possible options, and so do the other 3 coins. So 2 times 2 times 2 times 2 = 16. The answer is A. I hope this helped! Please give brainliest!
Answer:
table; occur; tally mark
Step-by-step explanation:
You would use a table to keep track of a distribution of data. You would have to wait for such data to occur. You could use tally marks to keep track to the data.
Hope this helps.
Sorry if it's wrong though.
