Answer:
a.) one sample t test
b.) H0 : μ = 59.3
c.) H1 : μ > 59.3
d.) μ = 59.3 ; σ = 39.84
e.) xbar = 79.4 ; s = 61.36
Test statistic = 3.16
Step-by-step explanation:
Given the sample data:
49.00 49.00 49.00 49.00 49.00 63.00 63.00 63.00 63.00 63.00 199.00 199.00 199.00 199.00 199.00 38.00 38.00 38.00 38.00 38.00 48.00 48.00 48.00 48.00 48.00 49.00 63.00 199.00 38.00 48.00
Sample size, n = 30
Using calculator :
xbar from the data above = 79.4
Standard deviation = 61.359
H0 : μ = 59.3
H1 : μ > 59.3
Test statistic :
(Xbar - μ) ÷ (σ/sqrt(n)
σ = 34.83
(79.4 - 59.3) ÷ (34.83/sqrt(30))
20.1 ÷ 6.359
Test statistic = 3.16
Multiply 9 and 5 then multiply by .5 giving you 22.5 so I’d say that’s your best option
Answer: B
Step-by-step explanation:
A proper fraction is when a fraction has the numeration less than the denominator

Answer:
6
Step-by-step explanation:
-A sample space is statistically defined as the possible number of outcomes.
-A cube has a total of six sides.
-The result of each toss can result in any one of the 6 faces with equal probability.
-The sample space is therefore 6
