All else being equal, if you cut the sample size in half, how does this affect the margin of error when using the sample to make

a statistical inference about the mean of the normally distributed population from which it was drawn? M E = StartFraction z times s Over StartRoot n EndRoot EndFraction. The margin of error is multiplied by StartRoot 0.5 EndRoot. The margin of error is multiplied by StartRoot 2 EndRoot. The margin of error is multiplied by 0.5. The margin of error is multiplied by 2.

1/4 foot every 3/4 hour how many feet in one hour
RUDIKE [14]

For this case we propose a rule of three:

\frac {1} {4} foot -------------> \frac {3} {4} hour

x -----------------------------------> 1 hour

Where "x" represents the amount of foot in one hour.

x = \frac {1 * \frac {1} {4}} {\frac {3} {4}}\\x = \frac {\frac {1} {4}} {\frac {3} {4}}\\x = \frac {4 * 1} {3 * 4}\\x = \frac {4} {12}\\x = \frac {1} {3}

So, we have\frac {1} {3} foot every hour.

Answer:

\frac {1} {3}foot every hour

In a game, 3 people are chosen in the first round. Each of those people chooses 3 people in the second round and so on. How many
tatiyna

Answer:

729 people chosen

Step-by-step explanation:

4 calculations in head when 3^2 = 9

3 calculations in head when 3^3 = 27

2 calculations in head when 3^4 = 81

1 calculations in head when 3^5 = 243

Answer found 3^6 = 729.

3  = 1st       = 3^1

9  = 2nd    = 3^2         3(3)

27  = 3rd   = 3^3         9(3)

81  = 4th    = 3^4        27(3)

243 = 5th  = 3^5       81(3)

729 = 6th = 3^6        243(3)
