Answer:
6 brochures
Step-by-step explanation:
Each brochures is 23 centimeters wide.
The table is 1.5 meters wide.
To know how many brochures can be placed side by side on the table first you have to calculate how many centimeters there are in 1.5 meters wide.
One meter equals 100 centimeters.
Therefore in 1.5 meters there are:
centimeters.
Now we must calculate in how many parts of 23 cm can be divided 150 cm.
To do this we made the division of 150 between 23
This means that up to 6 brochures of 23 cm can be placed side by side on the table
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
