Solution Steps

To simplify the given expression, we need to follow the order of operations (PEMDAS/BODMAS). First, simplify the expressions inside the parentheses, then perform the multiplications, and finally, handle the addition and division.

Step 1: Simplify the Numerator

First, we simplify the numerator: 2⋅(5+2)+2⋅5=2⋅7+2⋅5=14+10=24 2 \cdot (5 + 2) + 2 \cdot 5 = 2 \cdot 7 + 2 \cdot 5 = 14 + 10 = 24

Step 2: Simplify the Denominator

Next, we simplify the denominator: 2⋅(8−1)=2⋅7=14 2 \cdot (8 - 1) = 2 \cdot 7 = 14

Step 3: Divide the Numerator by the Denominator

Now, we divide the simplified numerator by the simplified denominator: 2414=127≈1.7143 \frac{24}{14} = \frac{12}{7} \approx 1.7143

Final Answer

The simplified value of the given expression is: 1.7143 \boxed{1.7143}

Positive events are great, but recent research suggests that unexpected positive outcomes (e.g., an unseasonably sunny day) predict greater-than-normal amounts of risk-taking and gambling (Otto, Fleming, Glimcher, 2016). Researchers demonstrated this by comparing lottery sales-indicative of risk-taking-on normal days with lottery sales on days when some unexpected positive event occurred in the city. They observed increased sales after unexpected positive outcomes. Suppose that a researcher extends this observation to the laboratory and randomly assigns participants to two groups. Group 1 receives an unexpectedly large payment for participating and Group 2 receives the expected amount of compensation. The researcher then measures how much money the participants are willing to gamble in a game of chance. Unexpected Positive Outcome Expected Outcome --- --- n=16 n=16 M=5.75 M=5.00 SS=6.5 SS=10.0 Test the one-tailed hypothesis that an unexpected positive outcome increased the amount of money that participants were willing to gamble. Use a α=.01.
