As the coin is tossed upwards an upwards force acts on it and this force decreases up to the highest point the coin reaches. at the highest point the force of gravity applies. This force is downwards and constant (9.8m/).
Answer:
There is no difference in the number of sales between The Florida salespeople and Washington salespeople
Sp^2 = 39
Step-by-step explanation:
Given data :
Florida: 39, 44, 42, 50, 55, 48, 51, 38, 54
Washington: 42, 43, 56, 50, 49, 52, 53, 56
number of sales persons in Florida = 9
number of sales persons in Washington = 8
variance = constant
a)Determine if there is difference between the Florida salespeople and Washington salespeople
we will carry out a two tailed test based on the given data
H0 : u1 = u2
H1 : u1 ≠ u2
x ( mean ) = 46.77, y ( mean ) = 50.13 ,
s1^2 = 39.69, s2^2 = 28.41, n1 = 9 , n2 = 8
therefore :
Sp^2 = = 38.96 ≈ 39
performing test statistic
t = =
= -1.1078
critical value is at t = 0.05 and for a two tailed test it is at 2.13 therefore e accept H0 at 5% . This shows that there is no difference in sales
