In lobbying congress for action to correct the ozone depletion problem, the environmental group save planet earth claims that 70% of the population supports the ban on household aerosols. in a survey by media general and the associated press, 150 of the 200 respondents indicated support for a ban on household aerosols. test the claim, at the 1% significance level, that more than 70% of the population supportsthe ban on household aerosols.

There is no statistical evidence to support  the claim, at the 1% significance level, that more than 70% of the population supportsthe ban on household aerosols

Step-by-step explanation:

(right tailed test for proportion at 1% significance level)

Sample proportion p=

p difference = -0.05

Std error for p =

Test statistic  z = p diff/std error

= -1.543

p value = 0.0614

since p >0.01 our alpha we accept H0

There is no statistical evidence to support  the claim, at the 1% significance level, that more than 70% of the population supportsthe ban on household aerosols

answer:

step-by-step explanation:

20% of 3.50 = .7 3.50 - .7 = 2.8     10% of 2.80 = .28   2.80 - .28 = 2.52

so the answer 2.52
