Americans typically eat quickly and do not spend time enjoying their meal. A researcher plans to test if those trained in mindfulness will take more time to enjoy their meal (that is, they will spend more time eating than the general population). The general population spends an average of 68 minutes per day combined eating their three meals. The researcher plans to do a single-sample t-test after the data are collected. What is the null hypothesis for this test? Question 12 options: The group trained in mindfulness will spend less time eating than the general population The group trained in mindfulness will not spend less time eating than the general population The group trained in mindfulness will spend either more or less time eating than the general population The group trained in mindfulness will spend more time eating than the general population

Step-by-step explanation:

The null hypothesis is the starting point. A researcher plans to test if those trained in mindfulness will take more time to enjoy their meal (that is, they will spend more time eating than the general population). This is the starting point point which we presume to be true. Therefore, the null hypothesis for this test would be:

The group trained in mindfulness will spend more time eating than the general population.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
