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: 36
Step-by-step explanation:
10^2 -4^2 = x^2
100 -16 = x^2
84= x^2
Find the square root of 84 which is approximately 9.2
The answer is 9.2
Basically, the higher the price an item is the more you will be taking off of it if it is 10 percent off. For example, at $50, 10 percent off is $5, but at $55, it’s $5.50. There is more to take away, making the final price less than the original. Hope that make sense!
Answer: The team's win-loss record that year is 1.7
Step-by-step explanation:
During the 2017 Major League Baseball season the Cleveland Indians played 162 games.
Let x = the number of games that the
Cleveland Indians lost during the 2017 Major League Baseball season.
This means that the number of games that the Cleveland Indians won during the 2017 Major League Baseball season would be x + 42.
Total number of games played = sum of games won + sum of games lost. This is expressed as
162 = x + 42 + x
2x + 42 = 162
2x = 162-42 = 120
x = 120/2 = 60
Number of games that the Cleveland Indians lost during the 2017 Major League Baseball season is 60
The number of games that the Cleveland Indians won during the 2017 Major League Baseball season is 60 + 42 = 102
The team's win-loss record that year
would be wins/loses
= 102/60 = 1.7
