Is the right arm or left arm stronger? Twenty five right handed people were studied. They were asked to do as many bicep curls a

s possible, first with their right arm and then with their left arm. Note:The differences were calculated as right-left.The 95% confidence interval for the true mean difference is (-9.242, 0.2472). Which of the following statements is the correct interpretation?A. The p-value should be smaller than 0.05.B. The p-value should be higher than 0.05.C. The p-value should be smaller than 0.95.D. The p-value should be smaller than 0.95.

Answer:

B. The p-value should be higher than 0.05

Step-by-step explanation:

p-value is smaller than 0.05 means that there is significant difference in mean bicep curls made with right hand and left hand.

Since 95% confidence interval for the true mean difference is given as  (-9.242, 0.2472), and confidence interval includes the value 0, we cannot say that there is significant difference. Therefore p-value is not smaller than 0.05, it is higher than 0.05.

Answer:

4 bags

Step-by-step explanation:

The way to read a step and leaf diagram is to consider the "stem" as the tens digit and "leaf" ans the ones digit.

So "0" in stem and "5" in leaf would be the number "05" or simply "5"

Also, "2" in stem and "4" in leaf would be the number "24"

When we have more numbers in leaf, they are basically different numbers. So lets list the numbers from stem-and-leaf plot:

5, 24, 30, 34, 65, 70, 74, 87, 90

The question asks for how many numbers are there LESS THAN 40?

the numbers less than 40 are:

5, 24, 30, 34

That is 4 numbers

28.2% of 92 this is for math
romanna [79]

Hey there!

Usually when you come across the word “of” in mathematical problems , it simply means that you’re multiplying

So we can simply multiply 28.2% from 92

28.2% = 28.2/100 = 0.282

New equation

0.282 * 92 = the answer

0.282 * 92 = 25.944

Good luck on your assignment and enjoy your day!

Let a_1 = 5

Let d = 5 = common difference

S_n = a_1 + (n - 1)d

What is the area of the polygon?
Delvig [45]
Find the area of the triangle on top
A=(.5)(Base)(Height)
A=(.5)(15)(9)
A=67.5

In the rhombus below you can move the corner triangle to the other side to transform it into a rectangle with a sides of 7 and 15.  so lets find the area of this rectangle
A=L*W
A=15*7
A=105

now combine the two areas
67.5+105
172.5
so answer "C"

The sum of two consecutive integers is 183. What is the smaller integer?
Natali5045456 [20]
91

Explanation: Since the ones digit ends in a 3, that means the the ones digits of the two consecutive integers must be 1 and 2 or 6 and 7. However, you see 18 in the number 183. 9 + 9 = 18. When you add 6 and 7, you have to carry over one. However, when you add 1 and 2, you do not. Therefore, the two consecutive numbers are 91 and 92. 91 is the smaller integer, so that is the answer.
