Let x be a random variable representing dividend yield of Australian bank stocks. We may assume that x has a normal distribution

kotegsom [21]

Answer:

a) 0.025 level of significance

The calculated t - value t = 2.88 > 3.58 at 0.025 level of significance

Therefore null hypothesis is rejected

The data indicate that the dividend yield of all Australian bank stocks is higher than 7.9%

Step-by-step explanation:

Let 'x' has a normal distribution

Given sample size 'n' =11

Mean of the sample (x⁻) = 9.89% = 0.0989

Standard deviation of the sample (s) = 2.3% = 0.023

Mean of the Population ' μ' = 7.9% = 0.079

<u><em>Null hypothesis:H₀:</em></u>' μ' = 0.079

<u><em>Alternative Hypothesis</em></u> :μ' > 0.079

Test statistic

$t = \frac{x^{-} -mean}{\frac{S}{\sqrt{n} } }$

$t = \frac{0.0989-0.079}{\frac{0.023}{\sqrt{11} } }$

t = 2.8840

Degrees of freedom

ν = n-1 = 11-1 =10

<em>Level of significance </em>

$t_{\frac{\alpha }{2} } = t_{\frac{0.05}{2} } = t_{0.025}$

$t_{0.025} , 10 = 3.5814$

<em>The calculated t - value t = 2.88 > 3.58 at 0.025 level of significance</em>

<em>Therefore null hypothesis is rejected</em>

<em>The data indicate that the dividend yield of all Australian bank stocks is higher than 7.9%</em>

Solve the system<br> 4x + 2y = 10<br> x = y + 13

Maslowich

Answer:

$x = 6$

$y = -7$

Step-by-step explanation:

We have the system of equations:

$4x+2y=10\\x=y+13$

Let's solve by substituting. We know that $x=y+13$ , so we can substitute $y+13$ in as $x$ in the equation $4x+2y=10$ .

$4(y+13) + 2y = 10$

Simplify this down so that we have $y$ on one side of the equation:

$4y + 52 + 2y = 10\\\\6y + 52 = 10\\\\6y = -42\\\\y = -7$

Now that we know the value of $y$ , we can substitute it in to the equation $x = y+13$ to find $x$ .

$x = -7+13\\\\x = 6$

Hope this helped!

Can you tell me what -15 + 4 equals and the process of how you got that answer

Bogdan [553]

-15 is 15 below o

you are adding 4 , so you are getting closer to 0

so you would actually use subtraction, 15-4 = 11

since 15 is negative, and you are adding a number smaller than 15, the answer would be negative so it would be -11

Compute the total and annual return on the following investment Two years after paying 53500 for shares in a startup company you

wel

Answer:

-46.91%

Step-by-step explanation:

Given:

Cost of buying the shares = $53,500

Selling cost of the shares = $3,300

Number of years = 2

Since the selling cost is less than the buying cost, therefore the statement for the loss can be verified

Now,

The loss = Selling cost - cost of buying = $3,300 - $53,500 = - $50,200

thus, the loss per year = $\frac{\textup{50,200}}{\textup{2}}$ = -$25100

Hence,

Rate of return = $\frac{\textup{Loss per year}}{\textup{Cost of buying}}\times100$

Rate of return = $\frac{\textup{-25100}}{\textup{53,500}}\times100$

Rate of return = -46.91%
