The online access computer service industry is growing at an extraordinary rate. Current estimates suggest that only 20% of the home-based computers have access to online services. This number is expected to grow quickly over the next 4 years. Suppose 25 people with home based computers were randomly and independently sampled. Find the probability that fewer than 10 of those sampled currently have access to online services.
It is believed that population standard deviation is 15 days. If test is conducted using 0.05 level of significance, what conclusion must be reached?
Evaluate the difference in the mean ratings and find the standard deviation of the difference in the ratings, what is the chance both children are boys?
The probability of the patient being chosen at random as having meningitis as only site of infection is?
Do these data suggest a statistically significance difference between the proportions of drug-resistant cases in the two states? Use a 0.02 level of significance and computed value of 2.37.
At the 0.01 level of significance, is there evidence to support the professor's claim?
Use this information to construct a probability table, and then calculate each of the following probabilities:
The populations must all be normally distributed, what is meant by normally distributed?
Of the adults in Jefferson County, 10% have had CPR training
Using a separate 2 by 2 table, compute predictive value positive and predictive value negative for population of 1,000 drug users.
Random samples of 25 observations were selected from each of 3 populations. For these data, SSTR= 120 and SSE = 216.
Describe appropriate treatment means μ1, μ2 and μ3. After that Test for statistically significant differences between these treatment means. Set α = 0.05.
Construct a 95% confidence interval for the average amount its credit card customers spent on their first visit to the chain's new store in the mall assuming that the amount spent follows a normal distribution.
