A smart phone manufacturer is interested in constructing a 95% confidence interval for the proportion of smart phones that break before the warranty expires. 82 of the 1635 randomly selected smart phones broke before the warranty expired. Round answers to 4 decimal places where possible. a. With 95% confidence the proportion of all smart phones that break before the warranty expires is between and b. If many groups of 1635 randomly selected smart phones are selected, then a different confidence interval would be produced for each group. percent of these confidence intervals will contain the true population proportion of all smart phones that break before the percent will not contain the true About warranty expires and about population proportion.

A smart phone manufacturer is interested in constructing a 95% confidence
interval for the proportion of smart phones that break before the warranty
expires. 82 of the 1635 randomly selected smart phones broke before the
warranty expired. Round answers to 4 decimal places where possible.
a. With 95% confidence the proportion of all smart phones that break
before the warranty expires is between
and
b. If many groups of 1635 randomly selected smart phones are selected,
then a different confidence interval would be produced for each group.
About
percent of these confidence intervals will contain the
true population proportion of all smart phones that break before the
