Step-by-step explanation:
Each year, the high school guidance counselors conduct a survey to estimate the proportion of students at the school who cheat on their homework. Based on a random sample of 300 students from the high school, a 99% confidence interval for the proportion of all students at the high school who cheat on their homework is 0.052 to 0.192. Describe how untruthful answers might lead to bias in this survey. Does the stated margin of error account for this possible bias
Answer:
The stated margin of error would account for the possible bias caused by wrong answers due to the closeness of the confidence interval
Step-by-step explanation:
Random sample = 300
99% confidence interval of student who cheat : 0.052 to 0.192
The confidence interval is too close that it only contains the population parameter, this means that almost every subject in the Given population will have to be measured.
Since This is an impractical approach it will lead to untruthful answers been produced which will cause bias. hence the stated margin of error would account for the possible bias caused by wrong answers.

Answer:
20 mm
95 mm
75 mm
3 inches
0.15 in/yr
Step-by-step explanation:
From the graph :
Sea height variation January 2000 = 20 mm
Sea height variation January 2020 = 95 mm
Difference in height variation :
Height 2020 - Height 2000
95mm - 20mm = 75mm
Expressing in inches
1mm = 0.04 inches
75mm = (75 * 0.04)in
= 3 inches
Rate of increase :
Difference in sea level height / difference in time
3 / (2020 - 2000)

In this article, Attitudes About Marijuana and Political Views (Psychological Reports, 1973), researchers reported on the use of cannabis by liberals and conservatives during the 1970s.
To test the claim (at 1% significance) that the proportion of voters who smoked cannabis frequently was lower among conservatives, the hypotheses were:
H0:p1−p2=0(p1=p2)
Ha:p1−p2<0(p1
In the hypothesis test about cannabis use by conservatives and liberals, the test statistic was z = -4.27, with a corresponding p-value of about 0.00001.
Which conclusion is most appropriate in the context of this situation?
Answer:
The pvalue of the test is 0.00001 < 0.01, which means that we have sufficient evidence to conclude that the proportion of voters who smoked cannabis frequently was lower among conservatives than liberals.
Step-by-step explanation:
We test:
If the proportion of voters who smoked cannabis frequently was lower among conservatives than liberals.
Corresponding p-value of about 0.00001.
The pvalue of the test is 0.00001 < 0.01, which means that we have sufficient evidence to conclude that the proportion of voters who smoked cannabis frequently was lower among conservatives than liberals.

Answer:
a = -10
Step-by-step explanation:
33 - 4a = 73
To get a by itself, you must move 33 to the other side. To this, you must subtract it from both sides, canceling it out on the left side.
You will be left with: -4a = 73-33
Subtract 73 and 33, which will get you 40.
Now the equation is -4a = 40
To get a by itself, divide -4 into both sides. Doing this will isolate a.
The equation you will have after that is a = 40/-4.
Divide 40 by -4, which will get you -10.
Therefore, a = -10.

ale mosquitos have pretty short lifespans. Males of a certain species have lifespans that are strongly skewed to the right with a mean of 888 days and a standard deviation of 666 days. A biologist collects a random sample of 363636 of these male mosquitos and observes them to calculate the sample mean lifespan. What is the probability that the mean lifespan from the sample of 363636 mosquitos \bar x x ˉ x, with, \bar, on top exceeds 101010 days
Answer:
0.0228 = 2.28% probability that the mean lifespan from the sample exceeds 10 days.
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Mean of 8, standard deviation of 6, sample of 36:
This means that [tex]\mu = 8, \sigma = 6, n = 36, s = \frac{6}{\sqrt{36}} = 1[/tex]
What is the probability that the mean lifespan from the sample exceeds 10 days?
This is 1 subtracted by the pvalue of Z when X = 10. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{10 - 8}{1}[/tex]
[tex]Z = 2[/tex]
[tex]Z = 2[/tex] has a pvalue of 0.9772
1 - 0.9772 = 0.0228
0.0228 = 2.28% probability that the mean lifespan from the sample exceeds 10 days.
