Question

Problem I: Pl The speeds (in megaherta) of 100 semiconductors are used to prodace the following histogran and descriptive statistics Histogram of Speed Descriptive Statistics: Speed Variable N Nean SE Mean StDev Minimunm Data 03 aximam 701.45 709 79 01 100 69s.24 .742 7.42 679.01 690.447 he shape of the distrbution of speed. Based on the shape of the distribution what would you prefer as measures of center and spread? Justify your answer. b) What is the approximate median speed of the semiconductors? e) Write down the five-number-summary of the speed of the semiconductors d) Calculate the interquarile range (IQR) of the data

Explanation / Answer

1. From the shape of the histogram we can say that distribution is normal.

For normal distribution mean= median = mode

2. Median = mean=695.24

3. Five number summary stat:

Minimum : 679.01

Q1 : 690.44

Q2: 695.24

Q3: 701.45

Max : 709.79

4. IQR = Q3 -Q1 =11.01
