Vaselesa [24]

<u>Solution and Explanation:</u>

a)  51% of users of mobile phones use their phone at least once per hour,

It is a binomial distribution with n = 150, p = 0.51

mean = np = 150 multiply with 0.51 = 76.5

SD= sqrt(np(1-p) )= 6.1225

Since np and n(1-p) > 5, we can assume the distribution is normal.

B) please see the attached file.

c)  It is a binomial distribution with n = 150, p = 0.02

mean = np = 150*0.02 = 3

SD= sqrt(np(1-p) )= 1.71464

Since np < 5, we cannot assume the distribution is normal.

depreciable amount/ useful life = depreciation per year

40,000/5 = 8,000

In some particular cases, the first year the asset enter the accounting it could be for a period of half the accounting period, so only half-year depreciation is appliedon the first year.

aleksley [76]

Answer: 0.050

LSL = 17.4

SD = 1.25

Cpk = Min{(mean - LSL / 3*sd), (USL - mean / 3*sd)}

= Min{ ( 18 - 17.4/ 3 * 1.25), (18.6 - 18 / 3 * 1.25)}

= Min { 0.05 0.05)

Cpk = 0.050
