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:
The value of s=10
Step-by-step explanation:
11+(-1)=10
Answer:
8
Step-by-step explanation:
8j-5+j=67
8J+j
9J-5=67
+5 +5
9J=72
/9 /9
j=8
If this helps please put brainliest
The answer is -10 because when u plug in -2 for x u get 4(-2)=-8 then -2+-8=-10
