2. What effect does increasing the sample size have on the mean of the sampling distribution?

1 answer:

8 0

With "infinite" numbers of successive random samples, the mean of the sampling distribution is equal to the population mean .As the sample sizes increase, the variability of each sampling distribution decreases so that they become increasingly more leptokurtic.

Help<br> Find the volume of this cone.<br> Use 3 for TT.

natima [27]

Answer:

$180ft^{3}$

Step-by-step explanation:

Volume of a cone:

$V=\pi r^{2} \frac{h}{3}$

Take $\pi$ as 3, as mentioned in the question

'r' is 'radius' ⇒ {diameter is given so divide by 2: 12/2 = 6}

'h' is 'height'

$V=(3)(6)^{2} (\frac{5}{3} )$

$V=(3)(36)(\frac{5}{3} )$

$V=108(\frac{5}{3} )$

{multiply 108 with 5 and then divide the answer by 3}

$V=108$ × $5$

$V=540$

$V=540/3$

$V=180ft^{3}$

A building across the street casts a shadow that is 2424 feet long. Your friend is 66 feet tall and casts a shadow that is 44 fe

salantis [7]

If 66 feet is a typo for 6 feet, then the answer is 330 feet long. Multiply 6•7.34= 44.04 round to 44. 2424/7.34= 330.245 round to 330. This is the height of the building.

If there is no typo 66/3= 22•2= 44

2424/3= 808•2= 1,616 feet tall.
