A car dealer who sells only late-model luxury cars recently hired a new salesman and believes that this salesman is selling at l

Natasha2012 [34]

Answer:

$t=\frac{5000-5600}{\frac{800}{\sqrt{16}}}=-3$

Explanation:

Data given and notation

$\bar X=5000$ represent the sample mean

$s=800$ represent the standard deviation for the sample

$n=16$ sample size

$\mu_o =5600$ represent the value that we want to test

$\alpha$ represent the significance level for the hypothesis test.

t would represent the statistic (variable of interest)

$p_v$ represent the p value for the test (variable of interest)

State the null and alternative hypotheses.

We need to conduct a hypothesis in order to determine if the mean is lower than 5600, the system of hypothesis would be:

Null hypothesis: $\mu \geq 5600$

Alternative hypothesis: $\mu < 5600$

We don't know the population deviation, so for this case is better apply a t test to compare the actual mean to the reference value, and the statistic is given by:

$t=\frac{\bar X-\mu_o}{\frac{s}{\sqrt{n}}}$ (1)

t-test: "Is used to compare group means. Is one of the most common tests and is used to determine if the mean is (higher, less or not equal) to an specified value".

Calculate the statistic

We can replace in formula (1) the info given like this:

$t=\frac{5000-5600}{\frac{800}{\sqrt{16}}}=-3$

Higher weight is given to sticks that have higher prices.

Rice weighted index is a good way to track track portfolio performance that best match for your portfolio.

In 2011 oil production in Libya was interrupted by political unrest. At the same time, the demand for oil by China continued to

vampirchik [111]

Answer:

Quantity of oil bought & sold would depend upon relative change i.e increase & decrease in demand & supply respectively.

↑Dd = ↓Sy : Qty same
↑Dd > ↓Sy : Qty ↑
↑Dd < ↓Sy : Qty ↓

Explanation:

Libya is an exporter of Oil to China. It implies china's demand for oil is satisfied by Libya's imports.

Usual markets are at equilibrium when market demand = market supply, demand & supply curves intersect.

Political unrest in Libya decreasing oil production, would decrease supply (exported) of oil to China & sift supply curve leftwards. Simultaneously, increase in China demand for oil would shift the demand curve rightwards. These changes in demand, supply would create excess demand. Excess demand would cause competition among buyers & increase the new equilibrium price.

However, Quantity of oil bought & sold would depend upon relative change , shift in demand & supply. If increase in demand is equal to decrease in supply, the quantity would remain same. If increase in demand is more than decrease in supply, quantity will increase. If increase in demand is less than decrease in supply, the quantity will decrease.
