Suppose the annual incidence of asthma in the general population among children 0-4 years of age is 1.4% for boys and 1% for girls.

If 10 cases are observed over 1 year among 500 boys 0-4 years of age with smoking mothers, then test whether there is a significant difference in asthma incidence between this group and the general population using the critical value method with a two sided test AND report a p value corresponding to your answer.

Answer #1

As you haven't provided the significance level, i am giving three critical value of z. However the conclusion regarding the rejection of null hypothesis will be same for all the three significance level, as our test statistic does not exceed any of the critical value of z.

Suppose the incidence rate of myocardial infarction (MI) per year was 5 per 1000 among 45- to 54-year old men in 2005. To look at changes in incidence over time, a random sample of 5000 45- to 54-year old men were followed for 1 year starting in 2015. Fifteen new cases of MI were found. The question is, how compatible is the sample rate of 0.3% with the population rate of .5%? A. Assess the statistical significance of this data...

A nutritionist claims that children under the age of 10 years are consuming more than the U.S. Food and Drug Administration’s recommended daily allowance of sodium, which is 2300 mg. To test this claim, she obtains a random sample of 16 children under the age of 10, and measures their daily consumption of sodium. The mean amount of sodium consumed is 2500 mg with a standard deviation of 320 mg. Is there significant evidence to support the claim of the...

In the past the average age of employees of a large corporation has been 40 years. Recently, the company has been hiring older individuals. In order to determine whether there has been an increase in the average age of all the employees, a sample of 25 employees was selected.

Researchers examined the relationship between Age (x) in years and blood-brain barrier (BBB) permeability (y) in transfer units. They collected a simple random sample of 24 adults from the New York City region and measured BBB permeability in the hippocampus. They decide to use least-squares regression to estimate the population regression line: μy=α+βx The results from their analysis include: a=0.67,b=0.016,s=0.0181,SEa=0.84,SEb=0.0037,r2=0.84 (a) What does the estimate of the slope for the least-squares regression line tells us? A. For every 1 year...
