olga_2 [115]

Answer:

Margin of Error=M.E= ± 0.0113

Explanation:

Margin of Error= M.E= ?

Probability that watched network news programs = p = 0.4

α= 95%

Margin of Error =M.E= zₐ/₂√p(1-p)/n

Margin of Error=M.E= ±1.96 √0.4(1-0.4)/7200

Margin of Error=M. E = ±1.96√0.24/7200

Margin of Error=M. E- ±1.96* 0.005773

Margin of Error=M.E= ±0.0113

The Margin of Error is the estimate of how much error is possible as a result of random sampling.

5. Assume a computer has a physical memory organized into 64-bit words. Give the word address and offset within the word for eac
spin [16.1K]

Answer:

see explaination and attachment

Explanation:

5.

To convert any byte address, By, to word address, Wo, first divide By by No, the no. of bytes/word, and ignores the remainder. To calculate a byte offset, O, in word, calculate the remainder of By divided by No.

i) 0 : word address = 0/8 = 0 and offset, O = 0 mod 8 = 0

ii) 9 : word address = 9/8 = 1 and offset, O = 9 mod 8 = 1

iii) 27 : word address = 27/8 = 3 and offset, O = 27 mod 8 = 3

iv) 31 : word address = 31/8 = 3 and offset, O = 31 mod 8 = 7

v) 120 : word address = 120/8 = 15 and offset, O = 120 mod 8 = 0

vi) 256 :word address = 256/8 = 32 and offset, O = 256 mod 8 = 0
