In the year 2000, the population of a certain country was 282282 million with an estimated growth rate of 0.70.7% per year. a. based on these figures, find the doubling time and project the population in 21002100. b. suppose the actual growth rates are just 0.2 percentage points lower and higher than 0.70.7% per year (0.50.5% and 0.90.9%). what are the resulting doubling times and projected 21002100 population? a. let y(t) be the population of the country, in millions, t years afte

Powerful women's group has claimed that men and women differ in attitudes about sexual discrimination. a group of 50 men (group 1) and 40 women (group 2) were asked if they thought sexual discrimination is a problem in the united states. of those sampled, 11 of the men and 19 of the women did believe that sexual discrimination is a problem. if the p-value turns out to be 0.035 (which is not the real value in this data set), then at = 0.05, you should fail to reject h0. at = 0.04, you should reject h0. at = 0.03, you should reject h0. none of these would be a correct statement.
