Find the χ2 statistic
Solution
The formula for calculating χ2 statistic is given by ;
χ2∗ =∑(Oi−Ei)2/Ei, where Oi and Ei is the i^th observation and the i^th expected count
From the given data calculated the expected count using the formula; E = (row total *column total)/sample size
χ2 = 7.104439336,
χ2 = 7.104 (rounded to 3 decimal .places)
The P-value is;
Degrees of freedom = (2-1)*(2-1) = 1, χ2 = 7.1044
P-value from chi-square calculator is 0.007689
Answer:
Increase, Decrease
Explanation:
A decrease in the supply results in many buyers competing for very few goods. If the demand is constant, the quantity supplied and price have an indirect relationship. A decrease in the volume of supplied results in an increase in price. Many buyers will be competing for a few products causing the equilibrium price to increase.
A decrease in supply will cause the quantity available for buyers to buy to decline. Consequently, the volume purchased will be fewer. Equilibrium quantity will, therefore, decrease.
Answer:
The total cost at 9000 anchor is $473400
Explanation:
To come up with the cost equation used by the manager, we need to find the variable cost per unit.
The total cost at production level of 5300 is = 5300 * 54 = $286200
Out of the total costs, $18000 are fixed.
Thus, variable costs at production of 5300 is = 286200 - 18000 = $268200
The variable cost per unit is = 268200 / 5300 = $50.60
Let x be the number of anchors produced.
The cost equation is = 18000 + 50.60x
At 9000 anchors, the total cost will be,
Total cost = 18000 + 50.60 * (9000) = $473400
<span>If I purchased 1,300 shares of lakeside bank stock for $23.32 a share. The total worth of the share is 1, 300 * 23.32 = $30, 316. Okay I received payments dividend worth 0.61 a share; that becomes 0.61 * 23.32 = $14.2252. I sold 1, 300 shares for $24.32. So I sold it for 1, 300 * 24.32 = $31616.
My total return = (Amount I sold the share + dividend received) - Amount I bought the share. So we have (31616 + 14.2552) - 30316 = $31630.2552 - $ 30, 316 = $1314.2552</span>
Answer:
The demand for money falls and the interest rate falls.
Explanation:
Price level can be described as the evaluation of the amount in which goods and services are sold in the market. A change in the price level can greatly affect the demand of a customer either positively or negatively.
A decrease in the price level enables a customer to purchase more products and at the same time save some amount of money, this results in the reduction of interest rates.
When the price level reduces, individuals will need less amount of money to buy the same quantity and type of product.
