**Finding Critical Values for a Left-tailed Z-Test**When performing a left-tailed z-test with a significance level (\(\alpha\)) of 0.05, it is essential to determine the critical value(s) and illustrate this on a graph. Follow the steps below:1. **Determine the Critical Value(s):** - Since \(\alpha = 0.05\), the critical value corresponds to the z-score at which 5% of the data lies to the left in the standard normal distribution. - Enter the critical value rounded to two decimal places. Use a comma to separate answers if more than one value is needed.2. **Graph the Rejection Region:** - Choose the correct graph from the options provided. **Graph Details:**- **Graph A:** This graph displays a blue shaded area on the left tail of the normal distribution curve. The shaded region lies to the left of the critical value on the \(x\)-axis, which indicates where the rejection region for \(\alpha = 0.05\) would typically be located.- **Graphs B, C, and D:** These images also show normal distribution curves with different shaded regions. For instance, the shaded areas in these graphs might indicate various positions on the curve relative to the critical values, signifying potential rejection regions based on different hypothesis test configurations.**Final Step:**- Click to select the graph that correctly represents the rejection region for a left-tailed test with \(\alpha = 0.05\). **Reminder:**- Understanding and correctly identifying the rejection region is critical for making accurate inferences in hypothesis testing. The left-tailed test assesses whether there is a significant decrease in the tested parameter, as indicated by the rejection region on the left side of the distribution.

The time it takes an employee to package the components of a certain product is normally distributed with ? = 7.5 and ? = 1.5 minutes. As an incentive, management has decided to give a bonus to the 25% of employees who took the shortest amount of time to package the components. Find the amount of time taken to package the components that will indicate that an employee should get a bonus. (Round your answer to two decimal places.) An employee must package components in a time minutes.
A recent study evaluated how addicted teenagers become to nicotine once they start smoking. The response variable was the number of yes answers on a questionnaire called the Hooked on Nicotine Checklist (HONC). Of teenagers who had tried tobacco, the mean HONC score was 3.8 (s = 4.4) for the 141 females and 2.4 (s = 3.5) for the 178 males. Complete parts a through c below. a.
