The claim is that the standard deviation of the speeds of drivers in Bradford is 8 mph. An experienced driver feels that this is very low. If a random speed check is conducted for 50 drivers, the standard deviation is 10.5 mph. Can we reject the null at
Answer:
Null hypothesis is rejected. Standard deviation is > 8 miles per hour
Step-by-step explanation:
σ [Population standard deviation] = 8 , s [sample standard deviation] = s
n [no of items] = 8
H0 [Null] : σ = 8 ; H1 [Alternate - Right Tail] : σ > 8
χ2 = (n - 1) . s^2 / σ^2
= 49 x (10.5)^2 / 82 = 5402.25 / 64
χ2 = 84.410
df [degree of freedom] = n -1 = 50 - 1 = 49
P value (χ^2 49 > 84.410) = 0.00125
p = 0.0013
p < α ie 0.05
So, H0 is rejected
Hence we state that standard deviation is > 8 miles per hpur

Using the algebraic expression 4n + 6, what is the greatest whole-number value that will give you a result less than 100?
Answer:
23
Step-by-step explanation:
Allow 4n+6=100
∴4n=94
∴n=23.5
If 23.5 gives you 100 exactly, the greatest whole number that'll give you a result less than 100 is 23.

An object is moving at a speed of 230 feet per week. Express this speed in inches per
minute. Round your answer to the nearest hundredth.
Answer:
Step-by-step explanation:
0.27 inches per minute....
An object is moving at a speed of 230 feet per week. This speed in inches per minute will be 0.27.
We know ,
1 feet = 12 inches and
1 week= 7days = 24×7 hours = 24×7×60 min.
= 10080 min.
Now, we just need to be careful with our multiplication and division. So we are going to have 230 times 12 on top divided by 24 times 7 times 60 i.e., 10,080 on bottom.
230 feet per week in inches per min = 230×12/10,080.
After evaluating and rounding up to 2 decimal places or the hundredth place , we will get our answer i.e., 0.27 inches/min.

1. Dear Math Helper,
I am in need of your help! I have a job where I design games. I am designing a game that involves a playing area
with 12 equal sections. Players randomly end up in one of the sections.
1 labeled one section, "Gain 40 points," four sections, "Gain 10 points," and the rest, "Try Again." Also, each
player automatically gives up 10 points with each move,
After trying out the game on some volunteers, I noticed that players tend to lose points in the long run. Without
changing the sizes of the sections, what adjustments can I make so that players are likely to earn at least one
Point in the long run?
Answer: Let them start off with a certain amount of money. So before they make a move they would have some points ahead of time.
Step-by-step explanation: Hope this helped!! :)
Well, you can actually increase the number of points for those sections and spread them across the sections so that as the players get in the long run, some points will be available for them.
What is video game?Video game refers to a device which is electronically controlled and played and involves the controlling of images displayed on the screen. Video games has really improved as technology keep advancing.
Thus, from the question above, if players will not lose points at the long run, then it's necessary points need to increase at the long run.
