The antibody production of 12 male red-winged blackbirds before and after receiving testosterone implants was compared. the units for antibody levels were natural log (10-3 optical density) per minute (ln(mod/ the mean change in antibody production was d = 0.056, and the standard deviation was sd = 0.183 if you were assigned the task of repeating this experiment, and wanted to ensure that you could detect a mean change of 0.02 units with a probability of 0.8, then what sample size would you use? since we are calculating n for a study of individuals, answers should be rounded up to the next whole number.

21/58.

hope to be marked brainliest

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
