Ascientist recently submitted a paper to a leading scientific journal. his data asset that a new drug combination is an effective treatment for strep throat. his study included six test subjects, four of whom received the new drug combination and two of whom received a placebo. all four subjects who received the drug combination were without symptoms after ten days of treatment. the paper was rejected. which of the following is the most likely reason for the rejection? a. the study was biased toward subjects receiving the drug combination. b. the study involves too small a sample size. c. the study involves too large a sample size. d. the study was biased toward subjects receiving the placebo.

Option B is correct.

Step-by-step explanation:

The following is the most likely reason for the rejection- the study involves too small a sample size. Only six persons were involved and this is a very small sample size. (his study included six test subjects, four of whom received the new drug combination and two of whom received a placebo.)

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2

0 and 5 minutes

step-by-step explanation:

given that one morning eight buses arrive late by the number of minutes given below:

0 8 2 6 9 2 0 7 8

write these in ascending order

0   0 2 6 7 8 8 9

in the afternoon two more buses arrive at the bus stop say by x and y minutes late.

total number of buses = 10

median = average of 4th and 5th after arranging in ascending order

since 4th entry is 6, the values of x and y should be below 6

also given 0 is the mode so either x or y or both should be 0 because then only 0 gets the maximum frequency and hence mode

thus we have

0 0 0 2 6 7 8 8 9 and another unknown entry which is below 6.

since median is 3.5, we have the unknown entry to be 5 only because then only median =( 2+5)/2

thus the after noon buses were late by 0 and 5 minutes.
