Let R^2 unrestricted and R^2 restricted be 0.4366 and 0.4149 respectively. The difference between the unrestricted and the restr

icted model is that you have imposed two restrictions.The number of regressors in the unrestricted model is 3. There are 420 observations. The F-statistic (under the assumption of homoskedasticity) in this case is:A) 4.61B) 8.01 C) 10.34 D) 7.71

Answer:

Option (B) is correct.

Explanation:

Given that,

R^{2}[tex/] unrestricted = 0.4366[tex]R^{2}[tex/] restricted = 0.4149Regressors in the unrestricted model = 3No. of observations, n = 420No. of independent variables, k = 3Degree of freedom i.e no. of restrictions, q = 2F-Statistic:[tex]=\frac{(\frac{R^{2} _{UR}-R^{2} _{R}}{q})}{\frac{1-R^{2} _{UR}}{(n-k-1)}}

=\frac{(\frac{0.4366-0.4149}{2}) }{\frac{1-0.4366}{(420-3-1)} }

=\frac{0.01085}{0.5634} \times 416

= 8.01

Suppose Charlene Brewster has timesâ (in seconds) of 8.5â, 8.5â, 8.3â, 8.6â, 8.7â, 8.4 and a performance rating of 85â%.
professor190 [17]

Answer:

1. 10s

2. Slower than normal

Explanation:

1. To calculate the normal time, we first take the average of Charlene's observed times:

Average of Charlene's observed time = \frac{(8.5+8.5+8.3+8.6+8.7+8.4)}{6}= 8.5s

Her normal time is therefore: \frac{Average of Charlene's observed time}{performance rating} = \frac{8.5}{0.85} = 10s

2. Since no of Charlene's observed time is higher than normal time of 10s, we can therefore conclude that her work perfomance should be rated as slower than normal.
