Step-by-step explanation:
We know that,

Where,
X = raw score = 84
μ = mean = 68
σ = standard deviation = 10
Putting the values,

The percent of his sales that were less than or equal to 84 inches, is

Therefore, the remaining 100-94.5=5.5% were more than 84 inches.

♡ The Explanation/Step-By-Step ♡
-
3.602 x 10 - 4
Multiply the numbers: 3.602 x 10 = 36.02
= 36.02 - 4
Subtract the numbers: 36.02 - 4 = 32.02!
= 32.02

Answer: 355.49
Step by Step:
82.14+9.77+31.35+41.25=164.51
520-164.51=355.49
Answer:
c) is true
Step-by-step explanation:
Given are four statements. Let us check one by one
a) If the calculated value of F statistic is higher than the critical value, we reject the alternative hypothesis in favor of the null hypothesis
False, we reject H0 in favour or alternate
b) The F statistic is always nonnegative as SSRr is never smaller than SSRur.
F statistics is non negative but reason is bot SSRr and SSRur are positive
Not because SSRr is never smaller than SSRur
c) Degrees of freedom of a restricted model is always less than the degrees of freedom of an unrestricted model.
This is true because in a restricted we put constraints thus df will be less
d) The F statistic is more flexible than the t statistic to test a hypothesis with a single restriction.
False. F statistic is for testing variances while t statistic for means.
