The difference between two sample teenage female and male depression rates is 0.07 . The estimated standard error of the sampling distribution is 0.040. What is the 95 percent confidence interval?
Homework Answers
confidence interval for (p1-p2)
=> (p1' - p2') - z*
p1-p2
to (p1' - p2') + z*p1-p2
Now, we have
p1' - p2' = 0.07, p1-p2
= 0.040
95% confidence interval z score = 1.96
Thus, 95% confidence interval
=> (0.07 - 1.96*0.04) to (0.07+ 1.96*0.04)
=> -0.0084 to 0.1484
=> (-0.0084, 0.1484)

Research question: In the population of all American adults, how strong is the relationship between age and reaction time? Data were collected from a representative sample of 500 American adults concerning their ages (in years) and reaction times (in milliseconds). What procedure should be used to estimate the strength of this relationship in the population? CI for single mean CI for single proportion CI for difference in means CI for difference in proportions CI for correlation 2Research question: To what...

The level of lead in the blood was determined for a sample of 152 male hazardous-waste workers age 20-30 and also for a sample of 86 female workers, resulting in a mean standard error of 5.8 +0.3 for the men and 3.8 + 0.2 for the women. Calculate an estimate of the difference between true average blood lead levels for male and female workers in a way that provides information about reliability and precision. (Use a 95% confidence interval. Round...

The USA Today reports that the average expenditure on Valentine's Day is $100.89. Do male and female consumers differ in the amounts they spend? The average expenditure in a sample survey of 40 male consumers was $135.67, and the average expenditure in a sample survey of 30 female consumers was $68.64. Based on past surveys, the standard deviation for male consumers is assumed to be $39, and the standard deviation for female consumers is assumed to be $17. 1.What is...

In studying his campaign plans, Mr. Singleton wishes to estimate the difference between men's and women's views regarding his appeal as a candidate. He asks his campaign manager to take two random independent samples and find the 95 % confidence interval for the difference. A random sample of 747 male voters and 731 female voters was taken. 392 men and 251 women favored Mr. Singleton as a candidate. Find this confidence interval. Step 3 of 4: Find the value of...
