Answer:
$33.81
Step-by-step explanation:
Strawberries = $2.49 Per Pound (Bought 3)
Blueberries = $3.19 Per Pound (Bought 2)
Pineapples = $4.99 Per Pound (Bought 4)
So we have to multiply each price with the number of fruits bought. 
So, For Example, Strawberries: <em>$</em><em>2</em><em>.</em><em>4</em><em>9</em><em> </em><em>×</em><em> </em><em>3</em><em> </em><em>=</em><em> </em><em>$</em><em>7</em><em>.</em><em>4</em><em>7</em>
After you did all three individually, add them all up.
Strawberries : <em>$</em><em>7</em><em>.</em><em>4</em><em>7</em>
Blueberries : <em>$</em><em>6</em><em>.</em><em>3</em><em>8</em>
Pineapple : <em>$</em><em>1</em><em>9</em><em>.</em><em>9</em><em>6</em>
<em>Total</em><em> </em><em>=</em><em> </em><em>$</em><em>3</em><em>3</em><em>.</em><em>8</em><em>1</em>

Answer:
(B) 0.2843 
Step-by-step explanation:
Let d be the difference in proportions from Country X and Country Y who were first married between the ages of 18 and 32. 
Then hypotheses are 
 : d=0.15
: d=0.15
 : d<0.15
: d<0.15
Test statistic can be found using the equation
 where
 where 
- p1 is the sample proportion of Country X (0.36)
- p2 is the sample proportion of Country Y (0.26)
- p is the pool proportion of p1 and p2 ( ) )
- n1 is the sample size of adults from Country X (60)
- n2 is the sample size of adults from Country Y (50)
Then  ≈ 0.5646
 ≈ 0.5646
p-value of test statistic is ≈ 0.2843
p-value states the probability that the difference in proportions between a random sample of 60 adults from Country X and a random sample of 50 adults from Country Y who were first married between the ages of 18 and 32 is at least 0.15
