<h3>Answer: Choice A</h3>
The first line shown in choice A is which means "the first term is -2"
The next line in choice A means "the nth term () is found by multiplying the prior term (
) by 8". Put another way: multiply each term by 8 to get the next term.
first term = -2
second term = 8*(first term) = 8*(-2) = -16
third term = 8*(second term) = 8*(-16) = -128
fourth term = 8*(third term) = 8*(-128) = -1024
and so on.
Answer:
a) The observed proportion of wallets that were returned
p = 0.45625
b) <em> 95% of confidence intervals for Population proportion</em>
<em> 0.40168 , 0.51082)</em>
<em>c) The lower bound of the 95% confidence interval = 0.40168</em>
<em>d) The upper bound of the 95% confidence interval = 0.51082</em>
Step-by-step explanation:
<u><em>Step(i)</em></u>:-
a)
Given data the researchers left a total of 320 wallets around Edinburgh, as though the wallets were lost. Each contained contact information including an address. Of the wallets, 146 were returned by the people who found them
Given sample size 'n' = 320
Given data 'x ' = 146
<em>Sample proportion </em>
<u><em>Step(ii)</em></u>:-
b)<em> </em><u><em>95% of confidence intervals for Population proportion</em></u>
Level of significance = 95% or 0.05%
<em>95% of confidence intervals for Population proportion are determined by</em>
<em></em><em></em>
<em></em><em></em>
<em>(0.45625 - 0.05457 , 0.45625 + 0.05457)</em>
<em>( 0.40168 , 0.51082) </em>
<em>c) The lower bound of the 95% confidence interval = 0.40168</em>
<em>d) The upper bound of the 95% confidence interval = 0.51082</em>
