Answer:
t=5.5080( to 3 d.p)
Step-by-step explanation:
From the data given,
n =20
Deviation= 34/20= 1.7
Standard deviation (sd)= 1.3803(√Deviation)
Standard Error = sd/√n
= 1.3803/V20 = 0.3086
Test statistic is:
t = deviation /SE
= 1.7/0.3086 = 5.5080
ndf = 20 - 1 = 19
alpha = 0.01
One Tailed - Right Side Test
From Table, critical value of t =2.5395
Since the calculated value of t = 5.5080 is greater than critical value of t = 2.5395, the difference is significant. Reject null hypothesis.
t score = 5.5080
ndf = 19
One Tail - Right side Test
By Technology, p - value = 0.000
Since p - value is less than alpha , reject null hypothesis.
Conclusion:
From the result obtained it can be concluded that ,the data support the claim that the mean rating assigned to the wine when the cost is described as $90 is greater than the mean rating assigned to the wine when the cost is described as $10.
Answer:
4K
Step-by-step explanation:
= K ( multiply both sides by 24 to clear the fraction )
J = 24K ( divide both sides by 6 )
= 4K
Answer:
No
Step-by-step explanation:
Because 4 cannat be mutiplyed into 45
Answer:
5
Step-by-step explanation:
To find the slope, rearrange the terms of this equation to y=mx+b form, where m is the slope.
Original equation: 5x-y=2
Subtract 5x to both sides: -y = -5x+2
Multiply both sides by -1: y = 5x-2\
This gives us the slope, which is equal to 5.
Let me know if this helps!
C is your answer
because (4, -6) is true, and it lies on both lines, which makes both equations true
hope this helps
