In a positively skewed distribution, the extreme scores are larger, thus the mean is larger than the median. Since the mean is 122, the only possible median is 118. Therefore, D.

Answer:

The possible value of median could be:

D. 118

Step-by-step explanation:

In positively skewed curve mean is greater than the median.

Here, mean=122

Hence, median<122

The only possible option in which median<122 is D.118

Hence, the possible value of median could be:

D. 118

A teacher was interested in knowing the amount of physical activity that his students were engaged in daily. He randomly sampled
klasskru [66]

Answer:

The standard error of the mean is 4.5.

Step-by-step explanation:

As we don't know the standard deviation of the population, we can estimate the standard error of the mean from the standard deviation of the sample as:

\sigma_{\bar{x}}\approx\frac{s}{\sqrt{n}}

The sample is [30mins, 40 mins, 60 mins, 80 mins, 20 mins, 85 mins]. The size of the sample is n=6.

The mean of the sample is:

\bar{x}=\frac{1}n} \sum x_i =\frac{30+40+60+80+20+85}{6}=52.5

The standard deviation of the sample is calculated as:

s=\sqrt{\frac{1}{n-1}\sum (x_i-\bar x)^2} \\\\ s=\sqrt{\frac{1}{5}\cdot ((30-52.5)^2+(40-52.5)^2+(60-52.5)^2+(80-52.5)^2+(20-52.5)^2+(85-52.5)^2}\\\\s=\sqrt{\frac{1}{5} *3587.5}=\sqrt{717.5}=26.8

Then, we can calculate the standard error of the mean as:

\sigma_{\bar{x}}\approx\frac{s}{\sqrt{n}}=\frac{26.8}{6}= 4.5

The pyramid shown has a square base that is 12 inches on each side. It has a surface area of 336 square inches. What is the slan
blagie [28]
Let b and h represent the length of the side of the base and the slant height, respectively. Then the total surface area is
  A = b² + 4*(1/2)bh
  A = b² +2bh

Substituting the given numbers, you have
  336 = 12² +2·12·h
  192 = 24h . . . . . . . . . subtract 12² = 144
  8 = h . . . . . . . . . . . . . divide by 24

The slant height is 8 inches.
