"Conservationists have despaired over destruction of tropical rain forest by logging, clearing, and burning." These words begin a report on a statistical study of the effects of logging in Borneo. Here are data on the number of tree species in 12 unlogged forest plots and 9 similar plots logged 8 years earlier:

The answer is "(0.461 , 7.206)"

Step-by-step explanation:

In the given question some information is missing, that is data. so, the correct answer to this question can be defined as follows:

UnLogged:

Logged:

formula of std error:

Point differential estimation =

For 90 percent t= 1.860 Cl & 8 df  

error of margin E =

Lower bound =mean difference -E=0.461

Upper bound = mean difference+ E=7.206

In the above 90% confidence interval were the population mean= (0.461 , 7.206)
