(05.07 MC) A study analyzed the average yearly salt intake in the United States from 2012 thru 2017. The data is summarized in the table:
Year
Annual Salt Intake
(grams)
2012 3,618
2013 3,646
2014 3,680
2015 3,716
2016 3.751
2017 3,790
The study found that the data after the year 2012 can be modeled by the function f(x) = 36.4x + 3,608, where x is the number of years since 2012 and f(x) is the total amount of salt
ingested in grams, Describe the significance of 3,608.

What is the solution to the equation? k/6.4=8.7 2.3 5.568 15.1 55.68

Need asap. solve for the following inequality

An automobile assembly line operation has a scheduled mean completion time, μ, of 12 minutes. the standard deviation of completion times is 1.6 minutes. it is claimed that, under new management, the mean completion time has decreased. to test this claim, a random sample of 33 completion times under new management was taken. the sample had a mean of 11.2 minutes. assume that the population is normally distributed. can we support, at the 0.05 level of significance, the claim that the mean completion time has decreased under new management? assume that the standard deviation of completion times has not changed.
