Answer:
The 98% confidence interval for the proportion of successful launches for the new rocket launching system is (0.553, 0.797).
Step-by-step explanation:
We have to calculate a 98% confidence interval for the proportion.
The sample proportion is p=0.675.
The standard error of the proportion is:
The critical z-value for a 98% confidence interval is z=2.326.
The margin of error (MOE) can be calculated as:
Then, the lower and upper bounds of the confidence interval are:
The 98% confidence interval for the population proportion is (0.553, 0.797).
