tyrone opens an account at the local bank by depositing $50 of his birthday money. He continues to deposit $50 each month for 5
Pavel [41]

<u>Answer-</u>

<em>The amount will be </em><em>$8944.62</em><em> after 5 years.</em>

<u>Solution-</u>

We know that,

\text{FV of annuity}=P[\dfrac{(1+r)^n-1}{r}]

Where,

P = Payment = $50 monthly

r = rate of interest compounded monthly= 3\frac{1}{4}=3.25\%=0.0325

n = number of period = 5 years = 5×12 = 60 months

Putting the values in the formula,

\text{FV of annuity}=50[\dfrac{(1+0.0325)^{60}-1}{0.0325}]

=50[\dfrac{(1.0325)^{60}-1}{0.0325}]

=50[\dfrac{6.8140-1}{0.0325}]

=50[\dfrac{5.8140}{0.0325}]

=50\times 178.8923

=8944.62

Therefore, the amount will be $8944.62 after 5 years.

Allen's hummingbird (Selasphorus sasin) has been studied by zoologist Bill Alther.† Suppose a small group of 10 Allen's hummingb
ruslelena [56]

Answer: provided in the explanation segment

Step-by-step explanation:

(a). from the question, we can see that since that б is known, we can use standard normal, z.

we are asked to find an 80% confidence interval for the average weights of Allen's hummingbirds in the study region. What is the margin of error?

⇒ 80% confidence interval for the average weight of Allen's hummingbirds is given thus;

x ± z * б / √m

which is

3.15 ± 1.28 * 0.32/√10

= 3.15 ± 0.1295 = 3.0205 or 3.2795

(b). normal distribution of weight (c) б is known

(c). option (a) and (e) are correct

(d).  from the question, let sample size be given as S

this gives';

1.28 * 0.32/√S = 0.15

√S = (1.28 * 0.32) / 0.15 = 2.73

S = 7.4529

cheers i hope this helps
