The number of defective light bulbs found in $10$ randomly selected shipments had a sample standard deviation of $4.2$ bulbs. Assume the number of defects follows a normal distribution. Using an $80\%$ confidence level, construct a confidence interval for the population standard deviation (${\sigma }^{}$). Also, interpret the results.

$(10.8,26.9)$

We are $80\%$ confident that the true population standard deviation in defective light bulbs per shipment is between $10.8$ and $26.9$

$(3.3,6.2)$

We are $80\%$ confident that the true population standard deviation in defective light bulbs per shipment is between $3.3$ and $6.2$ bulbs

$(10.8,26.9)$

We are $80\%$ confident that the true population standard deviation in defective light bulbs per shipment is greater than $10.8$ but less than $26.9$

$(3.3,5.2)$

We are $80\%$ confident that the true population standard deviation in defective light bulbs per shipment is greater than $3.3$ but less than $5.2$ bulbs.
