### Determining the Need for Recalibrating Cereal Box Filling EquipmentA plant manager is concerned that her equipment may need recalibrating due to fluctuations in the actual weight of the 19 oz cereal boxes it fills. The equipment requires recalibration if the standard deviation exceeds 0.7 oz. To determine if recalibration is needed, 71 randomly selected boxes of cereal from the next day's production were weighed. The standard deviation of these boxes was found to be 0.78. Using a significance level (α) of 0.1, we need to determine if the equipment requires recalibration.### Statistical Hypotheses- Null Hypothesis ($H_0$): $\sigma^2 =$- Alternative Hypothesis ($H_a$): $\sigma^2$ (choose appropriate comparison) 0.49 (since $0.7^2 = 0.49$)### Calculation Details- Degrees of Freedom (df) = - Chi-square Statistic ($\chi^2$) = - P-value = ### P-value ComparisonThe p-value is:- [ ] greater than $\alpha$- [ ] less than (or equal to) $\alpha$### Decision Based on Test StatisticThis test statistic leads to a decision to:- [ ] fail to reject the null- [ ] accept the null- [ ] accept the alternative- [ ] reject the null### ConclusionAs such, the final conclusion is that there is [ ] sufficient evidence to conclude the standard deviation in cereal box weight is [ ] than [ ].### Graphs / Diagrams ExplanationIf there are any graphs or diagrams, explain them in detail (none provided in the given image).For further information or questions about this topic, please refer to our detailed resources on hypothesis testing and standard deviation analysis.

A plant manager is concerned her equipment may need recalibrating. It seems that the actual weight of the 19 oz cereal boxes it fills has been fluctuating. The equipment needs to be recalibrated if the standard deviation exceeds 0.7 oz. In order to determine if the machine needs to be recalibrated, 71 randomly selected boes of cereal from the next day's production were weighted. the standard deviation of the 71 boxes was 0.78. Using a = 0.1, determine if the machine needs to be recalibrated. Ho:o? = H:o (Select an answer df = x² P-value = The p-value is... greater than a less than (or equal to) a

Engineers want to design seats in commercial aircraft so that they are wide enough to fit 90%of all males. (Accommodating 100% of males would require very wide seats that would be much too expensive.) Men have hip breadths that are normally distributed with a mean of 14.7in. and a standard deviation of 1.2in. Find P90. That is, find the hip breadth for men that separates the smallest 90% from the largest 10%. The hip breadth for men that separates the smallest 90%from the largest 10% is P90=nothing in. (Round to one decimal place as needed.)

Tom Sevits is the owner of the Appliance Patch. Recently Tom observed a difference in the dollar value of sales between the men and women he employs as sales associates. A sample of 40 days revealed the men sold a mean of $1,400 worth of appliances per day. For a sample of 50 days, the women sold a mean of $1,500 worth of appliances per day. Assume the population standard deviation for men is $200 and for women $250. At the .05 significance level, can Mr. Sevits conclude that the mean amount sold per day is larger for the women? (a)State the null hypothesis and the alternate hypothesis. (b) What is the decision rule? (c) What is the value of the test statistic? (d) What is your decision regarding the null hypothesis?
