What is different about the normality requirement for a confidence interval estimate of sigma and the normality requirement for

a confidence interval estimate of mu?
The normality requirement for a confidence interval estimate of sigma is ( less strict/ stricter) than the normality requirement for a confidence interval estimate of mu. Departures from normality have a (greater/ lesser) effect on confidence interval estimates of sigma than on confidence interval estimates of mu. That? is, a confidence interval estimate of sigma is (more/less)

robust against a departure from normality than a confidence interval estimate of mu.

Which ideas about functions are the most helpful​
avanturin [10]
Answer:
It helps in calculating the price of groceries such as fruits.
Step-by-step explanation:
Remember, functions are mathematical expressions that represent or shows the relationship between one or more variables.
For example, let's say a young girl wants to shop for 20 oranges in a mall. If we express the price using the function where;
y represents the total cost of the oranges,
20 represents the number of oranges,
x represents the cost per orange (assumed to $0.99)
Then, by means of the knowledge of function, the girl determines the total cost she to be $19.8 (20*0.99).

Which equation is satisfied by all of the plotted points?
Brums [2.3K]
The equation that is satisfied by all of the plotted points would be F. 3x because the y-intercept is at 0 so there wouldn't be one and the graph has a ratio of 3/1 so for every 3 numbers the line moves up it moves 1 space to the right, also indicating that it is positive.

Which of the following tables corresponds to the equation below?
Tresset [83]
Answer:
Option b

Explanation:
To solve this problem you need to plug in the values provided and determine if they make the equation true.

Step 1 - Plug in the values for x and y given in option a. Determine if all values make the equation true.

y = 3x + 1
1 = 3(0) + 1
1 = 1 {true}

y = 3x + 1
9 = 3(2) + 1
9 = 7 {not true}

Since the second ordered pair does not make the equation true, this is not the correct answer.

Step 2 - Plug in the values for x and y given in option b. Determine if all values make the equation true.

y = 3x + 1
1 = 3(0) + 1
1 = 1 {true}

y = 3x + 1
7 = 3(2) + 1
7 = 7 {true}

y = 3x + 1
19 = 3(6) + 1
19 = 19 {true}

Since all of the ordered pairs given in Option b make the equation true, this is the correct answer. To double check, you can do the same process for option c to make sure it is not true.

Step 3 - (Optional step) Plug in the values for x and y given in option c. Determine if all values make the equation true.

y = 3x + 1
-1 = 3(0) + 1
-1 = 1 {not true}

Since the first ordered pair given does not make the equation true, this is not the correct answer.
