Using traditional methods, it takes 94 hours to receive a basic driving license. A new license training method using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique with 40 students and observed that they had a mean of 95 hours. Assume the standard deviation is known to be 3. A level of significance of 0.02 will be used to determine if the technique performs differently than the traditional method. Find the value of the test statistic. Round your answer to 2 decimal places. Enter the value of the test statistic
Answer: the value of the test statistic is 2.11
Step-by-step explanation:
Given that;
sample mean x" = 95
standard deviation σ = 3
sample size n = 40
Null hypothesis H₀ : μ = 94
Alternative hypothesis H₁ : μ ≠ 94
Level of significance ∝ = 0.02
Test statistic value
z = (x" - μ) / ( σ/√n)
we substitute
z = (95 - 94) / ( 3/√40)
z = 1 / 0.4743
z = 2.11
Therefore, the value of the test statistic is 2.11

Which equation is represented by the graph?
y = -|x| + 2
y=-|x-2|
y=- |x|- 2
y=-|x+2|
Answer:
[tex]y = - |x| + 2[/tex]
Step-by-step explanation:
The graph is similar to Parabola. The transformation of graph is also similar to Parabola.
For B choice, the graph doesn't move by y-axis.
For C choice, the graph would have max-point at -2.
For D choice, similar to the B choice.

Answer:
4. x = 17
2. x = 77; y = 103
Step-by-step explanation:
4. The acute angles of a right triangle are complementary.
2x + 3x + 5 = 90
5x = 85
x = 17
2.
Same side interior angles are supplementary.
x + 103 = 180
x = 77
y and 103-deg angle are vertical angles, so they are congruent.
y = 103

A random sample of 450 vacationers in a huge luxury resort showed that 150 were business executives. We want to create a 95% confidence interval for the proportions of vacationers who are business executives.
a) What is the value at the centre of the 95% confidence interval? Write the symbol and value.
Answer:
p(s) = 0,33
Step-by-step explanation:
n = 450
p₀ = 150/450 p₀ = 0,33 then q₀ = 0,67
n*p₀ = 0,33*450 = 150
n*q₀ = 0,67*450 = 301
n*p₀ and n*q₀ more than 10, we can approximate the binomial to a Normal Distribution Distribution
a) p - p₀ = z(c) * √ (p₀q₀)/n
z(c) = ??
CI 95 % then α = 5 % α = 0,05 α/2 = 0,025
z(c) = 1,96
p = p₀ ± z(c) * √ (p₀q₀)/n
p = 0,33 ± 1,96 * 0,022
p = ( 0,33 - 0,04 ; 0,33 + 0,04
p = ( 0,29 ; 0,37 )
The value of the center of the confidence Interval is 0,33
p(s) = 0,33

4,500 pounds
3,500 pounds
1/4 ton
3 1/2 tons
Step-by-step explanation:
1 ton = 2000 pounds
2000+2500 = 45000 pounds
The total weight would be 4,500 pounds .

According to the question
You added 2,500 pounds and 1 ton
As we know
1 ton = 2,000 pounds
So,
Adding 1 ton and 2,500 pounds
= 2,000 pounds + 2,500 pounds
= 4,500 pounds
Hence, the total weight would be 4,500 pounds .
