Answer:
CPCTC
Step-by-step explanation:
The applicable reason for statement 4 is "Corresponding Parts of Congruent Triangles are Congruent (CPCTC)".
The reason shown in your problem statement is applicable only within one triangle. The segments of interest are in two different triangles.
Answer:
a) sample mean = 63
b) 95% confidence interval for the population mean wage (including benefits) for these employees is ( 60.58, 65.42 )
c) sample size is 26
Step-by-step explanation:
given the data in the question
a) estimate of the population mean
sample mean = ($63.00 per hour) = 63
b)
given that; standard deviation σ = 6.11, sample size n = 27
df = n-1 = 27 - 1 = 26
now at 95% CI, t will be;
∝ = 1 - 95% = 0.05, = 0.05/2 = 0.025
=
= 2.056
Margin of Error E = × (σ/√n)
Margin of Error E = 2.056 × (6.11/√27)
Margin of Error E = 2.056 × 1.17587
Margin of Error E = 2.4175 ≈ 2.42
CI estimate of the population mean will be; ( 95% )
- E < μ <
+ E
we substitute
63 - 2.42 < μ < 63 + 2.42
60.58 < μ < 65.42
Therefore, 95% confidence interval for the population mean wage (including benefits) for these employees is ( 60.58, 65.42 )
c)
At 90% confidence level and Margin of Error of 2
sample size n = ?
∝ = 1-90% = 0.10, ∝/2 = 0.10/2 = 0.05
=
= 1.645
Sample size n = ( × σ/ / E )²
we substitute
Sample size n = (1.645×6.11 / 2)²
n = (10.05095 / 2)²
n = ( 5.025475)²
n = 25.255
number of employed judges cant be decimal,
Therefore, sample size is 26
