An ethologist is interested in determining the average weight of adult Olympic marmots. It would be expensive and impractical to trap and measure the whole population, so a random sampleof 16 adults is trapped and weighed. The sample has a mean of 7.8 kg and a standard deviation of 0.49. Required:
a. Does the Central Limit Theorem apply?
b. What is the sampling distribution of the mean? In particular, what is the standard deviation of the sampling distribution of the mean, the standard error?
c. Find the 95% confidence interval for the average weight of adult Olympic marmots.

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

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
