The accompanying data on IQ for first-graders at auniversity lab school was introduced in Example 1.2.82 96 99 102 103 103 106 1
almond37 [142]

Answer:

Mean = 113.72

The estimator of 113.72 is point estimate used for the  conceptual population of all first-graders in this school

Step-by-step explanation:

Data provided in the question:

Data:

82 96 99 102 103 103 106 107 108 108 108 108 109 110 110 111 113 113 113 113 115 115 118 118 119 121 122 122 127 132 136 140 146

Number of data = 33

In the hint it is also given that the sum of the data value i.e ∑x = 3753

Now,

Point estimate of mean is given as;

Mean = \frac{\textup{Sum of all the data values}}{\textup{Total number of data value}}

or

⇒ Mean = \frac{\textup{3753}}{\textup{33}}

or

⇒ Mean = 113.72

Hence,

The estimator of 113.72 is point estimate used for the  conceptual population of all first-graders in this school

Find the surface area of the square pyramid below if the length of the sides of the base are 10 cm, and the slant height is 15 c
Damm [24]

The surface area of the square pyramid if the length of the sides of the base are 10 cm, and the slant height is 15 cm is 416.2 cm²

<h3>Surface area</h3>

Surface area of the square pyramid

= a² + 2a√a²/4 + h²

where,

  • a = sides of base = 10 cm
  • h = slant height = 15 cm

Surface area of the square pyramid

= a² + 2a√a²/4 + h²

= 10² + 2(10)√10²/4 + 15²

= 100 + 20√100/4 + 225

= 100 + 20√25 + 225

= 100 + 20√250

= 100 + 20(15.81)

= 100 + 316.2

= 416.2 cm²
