(1) In an investigation of toxins produced by molds that infect corn crops, a biochemist prepares extracts of the mold culture with organic solvents and then measures the amount of the toxic substance per gram of solution. From 6 preparations of the mold culture, the following measurements of the toxic substance (in milligrams) are obtained:1.4, 1.5, 1.8, 1.9, 2.5, 2.2Find a 99% confidence interval for the mean weight (in milligrams) of toxic substance per gram of mold culture in the sampled population.(2) Which of the following statements is true regarding part (a)?(A) The population mean must be inside the confidence interval. (B) The population does not need to be normal. (C) The population must be normal. (D) The population standard deviation ? must be known. (E) The population must follow a t-distribution.
Answer:
Following arew the solution to this question:
Step-by-step explanation:
Build the 99% trust period of harmful chemicals for both the community, because no information is provided mostly on population standard, they just use t-test procedure to find the necessary trust period.
The confidence interval of 99 percent for both the mean community is provided by,
[tex](\bar{x} \pm t_{\frac{\alpha}{2}} \frac{s}{\sqrt{n}})[/tex]
Use Minitab as seen below to get the necessary result:
T study one: weight
Variable N Mean stDev SE Mean 99% CI
weight 6 1.883 0.417 0.170 (1.197, 2.569)
The overall population weight of a toxic material in the above output is 99 percent (1.197, 2.569).
They may say of the 99% trust interval, the 99% trust between about 1.197 mg and 2.569 mg will lie throughout the average population.
Therefore, the option (A) is valid
One of conditions would be that the overall population should be standard in attempt to discover the standard deviation. This is the true option (C).

Jamal planted 53 fewer flowers than Heidi. Write an expression to show how many flowers Heidi planted.
Answer:
y = x + 53
Step-by-step explanation:
Let x be the number of flowers Jamal planted and y the number of flowers Heidi planted.
Jamal planted 53 fewer flowers than Heidi:
x = y - 53
Isolate the y.
x + 53 = y (Change the - sign to + sign when switching from different sides of an equation)
y = x + 53
Answer:[tex]j=h-53[/tex]
Step-by-step explanation:
Let h be the number of flowers Heidi planted, and j the number for Jamal.
[tex]j=h-53[/tex]

The expression 2y + 2.6 is equal to ? for y = 1.4
Answer:
5.4 :))
Step-by-step explanation:
ok so first you take 2*1.4=2.8 (you replace the Y with the number)
so now you have 2.8+2.6 which is equal to 5.4
Answer:
5.4
Step-by-step explanation:
2*1.4 is 2.8. Now the expression is y2+2.6=. Now, that we figured out what 2y is, which is 2.8, we need to add on 2.6. 2.6 + 2.8 is equal to 5.4. Now, to write out the whole equation, it would look like this.
2y+2.6=?
y2+2.6=?
2.8+2.6=?
5.4
So in the end:
2y+(2.6)= 5.4

An angle bisector sets up a triangle ratio that looks like the following proportion.
3x - 3 5x
====== = ====== Cross multiply
24 44
44*(3x-3) = 24*5x Remove the brackets on the left
132x - 132 = 24*5x Combine the right side
132x - 132 = 120x Add 132 to both sides
132x = 120x + 132 Subtract 120x from both sides
132x- 120x = 132 Combine
12x = 132 Divide by 12
x = 11

find the slope and y-intercept of the line in the graph. Express the answers as simplified fractions, if necessary.
Answer:
y=1 3/5x+-5
Step-by-step explanation:
So the y intercept is where your slope meets the middle, basically the y. So it hit the y on -5. And the rise and run 8/5 rise is 8 and run is 5. 8/5= 1 3/5. in equation it is y=1 3/5x+-5.
