ASAP. question 1, 2 & 3 please.

Q1 The following is a list of PE ratios (current stock price divided by company's earnings per share) for 23 companies 57,58, 30, 46, 42, 35, 31,56,52,48,48,41,37,34,30,40,40,40,34,36,38,39,13 Draw the stagram for these data using an initial class boundary of 295 and a dess width of 6. Note that you can add or remove classes from the figure. Label each class with its endpoints. 0:1 1:0 0 Q2 The following data are the ages (in years) of 16 history teachers in a school Gistrict. 47,34,42,47,31,41,26,49,48, 52, 33, 42, 54,40,32,55 Using the tool provided, construct a box-and-whisker plot for the data. ? Question 3 Fill in the POXx) values to give a legitimate probability distribution for the discrete random variable X, whose possible values are -1, 3, 4, 5 and 6 Values of $ 0 X 5 ?

these are more CLEAR, sorry about that.

Answer 1

Class interval midpoint fi (29.5,35.5) 35.5 7 (35.5.41.5) 41.5 7 (41.5.47.5) 47.5 (47.5,53.5) 53.5 4 (53.5,59.5) 59.5 2 درا Histogram 8 7 7 7 5 5 4 4 3 3 2 2 1 0 29.5 35.5 41.5 47.5 53.5 59.5 P/E Ratio

Class interval	midpoint	fi
(29.5,35.5)	35.5	7
(35.5,41.5)	41.5	7
(41.5,47.5)	47.5	3
(47.5,53.5)	53.5	4
(53.5,59.5)	59.5	2

x	P(X=x)
-1	0.3
3	0.26
4	0.12
5	0.11
6	0.21

Any values can be given so the sum should be 1.
