Answer 1

A) about 39.5%
b) +/ - 1.5%
c) I'd say no. It is very unlikely because less than the majority wanted it changed

Answer 2

Answer:

Step-by-step explanation:

Given that

The results of a survey show that the percent of adults in a certain town who want to change the name of the town is in the interval [0.38,0.41].

The interval has length as 0.03 and average or middle value is

0.395

a) POint estimate for the percent who want to change the town's name=

averge of the interval in percent = 39.5

b) Margin of error = 0.41-0.395 = 0.015

c) The town is not most likely to change its name.  Since the highest percent expected is only 41% which is very much below 50%

Hence the statistic t = (0.395-0.5)/sq rt 0.395(0.605)

influences this decision
