The rent for a one-bedroom apartment in Southern California follows the normal distribution with a mean of $2,200 per month and

a standard deviation of $250 per month. The distribution of the monthly costs does not follow the normal distribution. In fact, it is positively skewed. What is the probability of selecting a sample of 50 one bedroom apartments and finding the mean to be at least $1,950 per month?

Answer:

The probability is 1.

Explanation:

Despite that the he distribution is positively skewed, the distribution of sample means of one-bedroom apartments  will still be a a normal distribution based on Central Limit Theorem.

Since we have

μ = mean = 2200

SD = standard deviation  = 250

n = sample size = 50

Therefore,

Standard error = SD ÷ √n

                        = 250 ÷ √50

                        = 250 ÷ 7.07106781186548

                        = 35.3553390593274  approximately 35.36

Standardize xbar to z = (xbar - μ) ÷ (SD ÷ √n)

Therefore, we have:

P(xbar > 1,950) = P(z > (1,950 - 2200) ÷ 35.36)

                        = P(z > - 250 ÷ 35.36)                      

                        = P(z > -7.07) = 1

Therefore, the probability of selecting a sample of 50 one bedroom apartments is 1 which can be said to be certain.

Answer:

1.93%

Explanation:

The time weighted rate of return will be computed by combining the return at every time period demarcated by a withdrawal/addition.

<em>Time 1: Jan 1, 2016 to Sep 30, 2016</em>

start value = 100,000; end value = (105,000+5,000) = 110,000

Return = \frac{110,000}{100,000}=1.1

<em>Time 2: Sep 30, 2016 to Sep 30, 2017</em>

start value = 105,000; end value = 108,000

Return = \frac{108,000}{105,000}=1.028571

<em>Time 3: Sep 30, 2017 to Dec 31, 2017</em>

start value = (108,000 + 3,000) = 111,000; end value = 100,000

Return = \frac{100,000}{111,000}=0.900901.

Therefore, time weighted return

= (1.1 * 1.028571 * 0.900901) - 1

= 0.019305

= 1.93%.

The proceeds of a 10,000 death benefit are left on deposit with an insurance company for seven years at an annual effective inte
11111nata11111 [884]

Answer: $135

Explanation:

First find the future value of the proceeds.

= 10,000 * (1 + 5%)⁷

= $14,071

The monthly payments are equal so X is an annuity and as the payment is made immediately, this is an Annuity due.

Convert the interest rate into monthly figure:

= 3%/12

= 0.25%

Present value of annuity = Annuity * (( 1 - (1 + r)^-n ) / r) * (1 + r)

14,071 = Annuity * ((1 - (1 + 0.25%) ⁻¹²⁰) / 0.25%) * (1 + 0.25%)

14,071 = Annuity * 103.82

Annuity = 14,071 / 103.82

= $135.53

= $135
