confused on what your asking, please reask.. =)
Answer: Lower CI=21-t(0.025, 16)*7/sqrt(17)=21-2.12*7/sqrt(17)=17.4
upper CI=21+t(0.025, 16)*7/sqrt(17)=21+2.12*7/sqrt(17)=24.6
Explanation: Because there both close and equal
The correct answer is - b. Savannas have shrubs and isolated trees, while grasslands contain grasses, flowers, and herbs.
The difference of the two mainly comes as a result of the climate that affects this regions. Even though both of them are predominantly lands covered with grasses, there are differences that are obvious.
The grass in the savanna is yellow and dried for the biggest part of the year, there's also lots of shrubs, and also small communities of trees that are on certain distance from one another.
The grass in the grasslands is green for the biggest part of the year because there's much more rain which is also better distributed throughout the year. This also allows lots of flowers and herbs to grow in the grasslands, thus making it have a nice spectrum of colors in between the greenness.
