Gender and Frequency of Status Updates on Facebook The Pew Research Center conducted a survey of randomly sampled American adults, asking them about their use of social networking sites such as Facebook. The table below shows the self-reported frequency of status updates on Facebook by gender.

APPLIED STATISTICS AND PROBABILITY FOR ENGINEERS > CORRELATION In an article in IEEE Transactions on Instrumentation and Measurement (2001, Vol. 50, pp. 986–990), researchers reported on a study of the effects of reducing current draw in a magnetic core by electronic means. They measured the current in a magnetic winding with and without the electronics in a paired experiment. Data for the case without electronics are provided inthe following table. See the attached photo Answer the following: a. Graph the data and fit a regression line to predict current without electronics to supply voltage. Is there a significant regression at α = 0.05? What is the P-value?b. Estimate the correlation coefficient.c. Test the hypothesis that ρ = 0 against the alternative ρ ≠ 0 with α = 0.05. What is the P-value?d. Compute a 95% confidence interval for the correlation coefficient.
Eggs Hens usually begin laying eggs when they areabout 6 months old. Young hens tend to lay smaller eggs,often weighing less than the desired minimum weight of54 grams.a) The average weight of the eggs produced by the younghens is 50.9 grams, and only 28% of their eggs exceedthe desired minimum weight. If a Normal model isappropriate, what would the standard deviation of theegg weights be?b) By the time these hens have reached the age of 1 year,the eggs they produce average 67.1 grams, and 98%of them are above the minimum weight. What is thestandard deviation for the appropriate Normal modelfor these older hens?c) Are egg sizes more consistent for the younger hens orthe older ones? Explain.

Using Excel Tablet’s hardness can be represented by its relative density and tensile strength. Studies have indicated that its tensile strength depends on the relative density, regardless of production shifts. Recently, a batch was found to produce cluster of tablets that show low relative density values of 68%, 74.3%, and 80.1%. Based on the current data in April 2022, what is the prediction of the tensile strength for such tablets? Present the requires analysis and comment on the validity of the model that you have used to carry out this prediction.
