Answer:

mean = 7.8, median =5, and mode(s) =5

the shape of the distribution is positive skewed

Step-by-step explanation:

Find the mean, median and mode(s) for

2, 17, 5, 3, 28, 7, 5, 8, 5, 6, 2, 12, 10, 4, 3

the mean = sum of (2, 17, 5, 3, 28, 7, 5, 8, 5, 6, 2, 12, 10, 4, 3)/15 =

= 7.8

the median = 2, 2, 3, 3, 4, 5, 5, 5, 6, 7, 8, 10, 12, 17, 28, = the middle value, the 8th value falls in the middle = 5

the mode is the most occurring value = 5

2. Without constructing a frequency distribution or graph, would you characterize the shape of this distribution as balanced, positively skewed, or negatively skewed?

positive skewed or Right skewed because the value of the mean is greater than the median

A right skewed histogram is a positive skewed histogram (which means the tail is longer the positive direction) that have its tail to the right.For a right skewed histogram the mean has a larger value that the median because the peak of the skewness fall in the median range then the mean follow to the right. and the data drive the mean value to the right which increase in value.

The formula C=5/9(F−32) can be used to convert temperature from Celsius (C) to Fahrenheit (F). The highest temperature ever reco

Softa [21]

Answer:

57 °C.

Step-by-step explanation:

The formula that is used to convert temperature from Celsius (C) to Fahrenheit (F) is given by :

$C=\dfrac{5}{9}(F-32)$ ...(1)

If T = 134° F, we need to convert the temperature in Celsius.

Put F = 134, in equation (1)

$C=\dfrac{5}{9}(134-32)\\\\=\dfrac{5}{9}\times 102\\\\=56.66^{\circ} C\\\\\text{or}\\\\T=57^{\circ} C$

So, the temperature on that day is 57 °C.

A 600g packet of biscuits costs $2.40. Calculate How much would a 200g packet cost?

sp2606 [1]

Answer:

$0.8

Step-by-step explanation:

There is a relation of direct proportion between quantity of biscuit and its cost.

Let 200 g biscuit will cost $x.

Therefore,

$\frac{600}{2.40} = \frac{200}{x} \\ \\ x = \frac{2.40 \times 200}{600} \\ \\ x = 0.4 \times 2 \\ \\ x = 0.8$

The principal randomly selected six students to take an aptitude test. their scores were: 81.4 78.6 71.3 77.8 76.9 77.7 determin

Firdavs [7]

The confidence interval is $77.28\pm 2.23$ .

We first find the mean. Add together all of the data points and divide by 6, the number of data points; the mean is 77.28.

Next we find the standard deviation. Find the difference between each data point and the mean; square it; find the sum; divide by the number of data points; take the square root. The standard deviation is 3.32.

To find the margin of error, we calculate the z-score associated with this level of confidence. 100-90 = 10% = 0.1; 0.1/2 = 0.05; 1-0.05 = 0.95. Using a z-table (http://www.z-table.com) we see that this is between two scores, 1.64 and 1.65; we will use 1.645.

The margin of error is given by
z * (σ/√n) = 1.645*(3.32/√6) = 2.23.

Thus the confidence interval is 77.28 +/ 2.23.

The circle below has a center H. Suppose that m FG=42. Find the following.

Dahasolnce [82]

The measure of angle FHG = 42 degrees. This is the same as the arc length.

The measure of angle FEG = 21 degrees. This is half the value of the arc length.
