Answer:
test statistic is ≈ -0.36
p-value is ≈ 0.64
There is no significant evidence that the average golfer can hit the ball more than 235 yards on average.
Step-by-step explanation:
a hypothesis test where H_0: mu = 235 and H_1:mu > 235
test statistic can be calculated as follows:
z=
where
- sample mean driving distance (233.8 yards)
- M is the average expected distance that the average golfer can hit the ball under null hypothesis. (235 yards)
- s is the standard deviation (46.6 yards)
- N is the sample size (192)
Then test statistic is z=
=-0.3568
p-value is 0.64 >0.05
There is no significant evidence that the average golfer can hit the ball more than 235 yards on average.
Answer: $30
Step-by-step explanation:
So if Bob sells his fish at a profit of $1.25 and he has 24 fish to sell then 1.25*24= 30
(I'm assuming what you mean by "how much money he will have" is profit)
Answer:
60
Step-by-step explanation:
y = k/x ( as y is inversely proportional to x)
yx = k
--> k = yx
k = (6)(10)
k = 60
Enjoy it. I hope it will help you.
First do 10 time 10, which gives you a hundred, then add two, and you get 102
Answer:
1) 11h - 25
2) 8
3) C
Step-by-step explanation:
1) 5h-9+-16+6h
+ and - together makes -
5h - 9 - 16 + 6h
Arrange the like terms together
5h + 6h - 9 - 16
= 11h - (9+16)
= 11h - 25
2) 4x+4=9x-36
Subtract 4x from both sides
4x+4-4x = 9x-36-4x
Cancl out 4x and -4x from the left side
4 = 9x - 4x -36
=> 4 = 5x -36
Add 36 to both sides
4+36 = 5x -36 + 36
Cancel out -36 and +36 from the right side
=> 40 = 5x
Flip both the sides of the equation
5x = 40
Dividing both sides by 5

Cancel out the 5's on the top and bottom of the left side
x = 8
3) 7x+5 = 4x+5+3x
Arrange the like terms together on the right side
7x+5 = 4x+3x+5
=> 7x+5 = 7x+5
Subtract 5 from both sides
7x+5-5 = 7x+5-5
Cancel out +5 and -5 on both the sides
7x = 7x
Divide both sides by 7

Cancel out the 7's from the top and bottom of both sides
x = x
which can be true for infinite value of x like 1=1, 2=2, 3=3,.............
