A recent study conducted by the state government attempts to determine whether the voting public supports a further increase in cigarette taxes to help the public schools. The opinion poll recently sampled 1500 voting age citizens. 622 of the sampled citizens were in favor of an increase in taxes. The state government would like to decide if there is enough evidence to establish whether the proportion of citizens supporting an increase in cigarette taxes is significantly greater than 66%. At what level of significance will the null hypothesis not be rejected?

Answer 1

Answer:

Answer:

0.001%

Step-by-step explanation:

Given that a recent study conducted by the state government attempts to determine whether the voting public supports a further increase in cigarette taxes to help the public schools

n = 1500

favour x = 622

Sample proportion p = $622/1500 = 0.4147$

$H_0: p = 0.66\nH_a: p >0.66$

(right tailed test)

Assume H0 to be true.

Std error = $\sqrt{(0.66*0.34)/(1500) } \n=0.01223$

p difference = -0.2453

Test statistic Z = $(-0.2453)/(0.01223) \n=-20.05$

p value <0.00001

Hence fon ull hypothesis not to be rejected significant level should be greater than 0.00001 or 0.001%

You buy 1.95 pounds of oranges and 1.65 pounds of apples. Oranges and apples sell for the same price per pound. The total cost, after using a 75¢-off coupon, is $2.49. If c represents the cost of the fruit in dollars per pound, what equation could you use to find the value of c?

Answers

Answer:

(1.95 +1.65)c -0.75 = 2.49

Step-by-step explanation:

The cost of the fruit is the cost per pound (c) multiplied by the number of pounds, 1.95 +1.65. After $0.75 is deducted, the total cost is $2.49. The equation that says this is ...

(1.95 +1.65)c -0.75 = 2.49

3.6c = 3.24 . . . . add 0.75, simplify

c = 0.9 . . . . . . divide by the coefficient of c

The cost of the fruit is $0.90 per pound.

You can use a calculator for this question. Greg builds a new pond which has a volume of 7.35 m3. It is 4.2 m long and 50 cm deep. What is the width of the pond? m

Answers

The formula of getting the volume of a regular prism is L x W x H = V.
Given: V: 7.35m3
L: 4.2 m
H: 50 cm (Convert this to meters) = 0.5m
W: ?
L x W x H = V
4.2 x W x 0.5m = 7.35m3
2.1m2 x W = 7.35m3 <-- Divide both sides by 2.1m2
The result would be W= 3.5m
So the width of the pond is 3.5m
