viva [34]3 years ago
3 0

Answer:

let's see what to do buddy...

Step-by-step explanation:

" First four terms " means :

t(1) , t(2) , t(3) , t(4)

t(1) = a(1) = 5(1) - 1 = 5 - 1 = 4 \\ t(2) = a(2) = 5(2) - 1 = 10 - 1 = 9 \\ t(3) = a(3) = 5(3) - 1 = 15 - 1 = 14 \\ t(4) = a(4) = 5(4) - 1 = 20 - 1 = 19 \\  \\ t(1) = 4 \\ t(2) = 9 \\ t(3) = 14 \\ t(4) = 19

So the first four terms

are : 4 , 9 , 14 , 19

Harper’s Index claims that 23% of American are in favor of outlawing cigarettes. You decide to test this claim and ask a random
alexandr402 [8]

Answer:

There is enough evidence not to reject the claim.

Step-by-step explanation:

H0: The population proportion of Americans in favor of cigarette outlawing is 0.23.

Ha: The population proportion of Americans in favor of cigarette outlawing is not 0.23.

Critical value approach

z = (p' - p) ÷ sqrt[p(1 - p) ÷ n]

p' is sample proportion = 54/200 = 0.27

p is population proportion = 23% = 0.23

n is number of Americans sampled = 200

z = (0.27 - 0.23) ÷ sqrt[0.23(1 - 0.23) ÷ 300] = 0.04 ÷ sqrt[8.855×10^-4] = 0.04 ÷ 0.0298 = 1.34

The test is a two-tailed test because the alternate hypothesis is expressed using not equal to.

Critical value at 0.05 significance level is 1.96

For a two-tailed test, the region of no rejection of H0 lies between -1.96 and 1.96

Conclusion:

Fail to reject H0 because the test statistic 1.34 falls within the region bounded by -1.96 and 1.96.

There is enough evidence not to reject the claim because the claim is contained in the null hypothesis (H0).
