A car manufacturer randomly samples and interviews 1,000 consumers in a target market. Of the 1,000 interviewed, 93 indicated that they are likely to purchase a car from this manufacturer. Keep as many decimals as possible in your computations, but enter the final answers to three decimal places. Define the parameter p of interest in full context. Compute the value of the statistic p. Compute the 95% confidence interval estimating p. O (0.069, 0.117) O (0.075, 0.111) O (0.111, 0.075) O (0.117, 0.069) Interpret the confidence interval in full context.

Transcribed Image Text:A car manufacturer randomly samples and interviews 1,000 consumers in a target market. Of the 1,000
interviewed, 93 indicated that they are likely to purchase a car from this manufacturer.
Keep as many decimals as possible in your computations, but enter the final answers to three decimal
places.
Define the parameter p of interest in full context.
Compute the value of the statistic p.
Compute the 95% confidence interval estimating p.
O (0.069, 0.117)
O (0.075, 0.111)
O (0.111, 0.075)
O (0.117, 0.069)
Interpret the confidence interval in full context.
Transcribed Image Text:Interpret the confidence interval in full context.
Using this interval, would you say that the proportion of consumers likely to purchase a car from this
manufacturer differs from 10%? That is, would you conclude HA:p#0.10 at the a = 0.05 level? Why or
why not?
