In a study of 250 adults, the average heart rate was 70 beats per minute. assume the population of heart rates is known to be approximately normal, with a standard deviation of 12 beats per minute. what does a margin of error of 2 for the 98% confidence interval of the average beats per minute mean? in a study of 250 adults, the average heart rate was 70 beats per minute. assume the population of heart rates is known to be approximately normal, with a standard deviation of 12 beats per minute. what does a margin of error of 2 for the 98% confidence interval of the average beats per minute mean?

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
