Given Information:
number of trials = n = 1042
Probability of success = p = 0.80
Required Information:
Maximum usual value = μ + 2σ = ?
Minimum usual value = μ - 2σ = ?
Answer:
Maximum usual value = 859.51
Minimum usual value = 807.78
Step-by-step explanation:
In a binomial distribution, the mean μ is given by
μ = np
μ = 1042*0.80
μ = 833.6
The standard deviation is given by
σ = √np(1 - p)
σ = √1042*0.80(1 - 0.80)
σ = √833.6(0.20)
σ = 12.91
The Maximum and Minimum usual values are
μ + 2σ = 833.6 + 2*12.91
μ + 2σ = 833.6 + 25.82
μ + 2σ = 859.51
μ - 2σ = 833.6 - 25.82
μ - 2σ = 807.78
Therefore, the minimum usual value is 807.78 and maximum usual value is 859.51

According to the null hypothesis, the test statistic of the proportion is of z = 120.1.
<h3>
What is the null hypothesis?</h3>
The claim is that the rate of nausea is greater than the 6% rate experienced by flu patients given a placebo. At the null hypothesis, we consider the claim as false, hence the null hypothesis is:
<h3>What is the test statistic?</h3>
The test statistic is given by:
In which:
is the sample proportion.
- p is the proportion tested at the null hypothesis.
In this problem, the parameters are:
Hence, the test statistic is given by:

A possible 5 digit registration number divisible by 5, 10 and 11 is: 10010
Answer:
1. y=4x-5 2. y=5x+3 3. y=-2x-8 4. 2/3x+2 5. y=-3/4x-2 6. 1/4x+7 7. -3x+2/3 8. 2/3x+10 9. -2x-1/2 10. -3/4x-3
Step-by-step explanation:
the slope always goes in front of the x and then the y-intercept goes after.
