Im.not sure but i tjink its 10
Answer:
Hello your question is not well written attached below is the complete question
answer :
a) smallest value = $0.405 million
largest value = $22 million
b) smallest value = $0.505 million
largest value = $9.332 million
Step-by-step explanation:
A) what are the smallest and largest yearly salary values in the population
smallest value = $0.405 million
largest value = $22 million
b) What are the smallest and largest sample mean in the sampling distribution
Smallest value = $0.505 million
Largest value = $9.332 million
note : values where gotten using statkey on the dataset NFLcontracts2015 as stated in the attached document ( question )
It would be 3.01 because 40.00-40.00 is 0 then take away the other numbers 3.68- 0.67 is 3.01
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Group 1:
μ1 = 59.7
s1 = 2.8
n1 = sample size = 12
Group 2:
μ2 = 64.7
s2 = 8.3
n2 = sample size = 15
α = 0.1
Assume normal distribution and equ sample variance
A.)
Null and alternative hypothesis
Null : μ1 = μ2
Alternative : μ1 < μ2
B.)
USing the t test
Test statistic :
t = (m1 - m2) / S(√1/n1 + 1/n2)
S = √(((n1 - 1)s²1 + (n2 - 1)s²2) / (n1 + n2 - 2))
S = √(((12 - 1)2.8^2 + (15 - 1)8.3^2) / (12 + 15 - 2))
S = 6.4829005
t = (59.7 - 64.7) / 6.4829005(√1/12 + 1/15)
t = - 5 / 2.5108165
tstat = −1.991384
Decision rule :
If tstat < - tα, (n1+n2-2) ; reject the Null
tstat < t0.1,25
From t table :
-t0.1, 25 = - 1.3163
tstat = - 1.9913
-1.9913 < - 1.3163 ; Hence reject the Null
