If mc008-1.jpg, what is f(5.9)?
yulyashka [42]
The answer:

the full question is if f(x) = 3 [ x - 2 ] , what is f(5.9)?

9
10
11
<span>12

</span>first, [x - 2 ] is called the integer part of x-2, 
generally, to compute f(c) where c is a real number, it is sufficient to substitute the value of x by c.
so <span>f(5.9) = 3 [ 5.9 - 2 ] =  3 [ 3.9 ]

 as we know that </span>[ 3.9 ]=3
<span>
therefore
</span>3 [ 3.9 ]<span>= 3x3 =9

the answer is 9</span>

1. The 2006 General Social Survey contains information on the number of hours worked by a respondent each week. The mean number
Vilka [71]

Answer:

A)σ_M = 1.2634

B) CI = (36.564, 41.516)

C) σ_M = 0.1151

Step-by-step explanation:

A) Formula for standard error is;

σ_M = σ/√n

We are given;

Mean; x¯ = 39.04

Standard deviation; σ = 11.51

Sample size; n = 83

Thus;

Standard error; σ_M = 11.51/√83

σ_M = 1.2634

B) formula for confidence interval is;

CI = x¯ ± z(σ_M)

z is critical value

At 95% Confidence interval, z = 1.96

Thus;

CI = 39.04 ± 1.96(1.2634)

CI = (39.04 + 2.476) and (39.04 - 2.476)

CI = (36.564, 41.516)

C) sample size is now increased to 10000

Thus,standard error is calculated as;

σ_M = 11.51/√10000

σ_M = 0.1151

A coin-operated drink machine was designed to discharge a mean of 6 ounces of coffee per cup. Suppose that we want to carry out
lesya [120]

Answer: H0 : u = 6 ounces

Ha : u not equal to 6 ounces

Step-by-step explanation:

The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is no different than its mean.

While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.

Therefore, for the case above;

H0 : u = 6

Ha : u not equal to 6.
