Answer:
a) No
b) No
c) P value is more than 0.05.   
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 12 ounces
Sample size, n = 49
P-value = 0.136
First, we design the null and the alternate hypothesis
 
We use One-tailed z test to perform this hypothesis.
a) Alpha, α = 0.05
Since, p-value > α, 
The null hypothesis should not be rejected. We accept the null hypothesis and reject the alternate hypothesis. We conclude that the average chip weight is 12 ounces per bag.
b) Alpha, α = 0.10
Since, p-value > α, 
The null hypothesis should not be rejected. We accept the null hypothesis and reject the alternate hypothesis. We conclude that the average chip weight is 12 ounces per bag. 
c) The evidence is statistically significant at the .05 level means that the p value is more than 0.05.

The given pyramid's total surface area is 3. 24.0 square feet.
Step-by-step explanation:
Step 1:
To calculate the surface area of the given figure, we need to find the surface areas of the different shapes in the figure.
There are 3 triangles and 1 square in the figure.
Step 2:
All the triangles are similar.
The surface area of a triangle = 
The similar triangles have a base length of 3 feet and a height of 2.5 feet.
The surface area of 1 similar triangle =  square feet.
 square feet.
The surface area for all the similar triangles =  square feet.
 square feet. 
Step 3:
The surface area of a square is the square of its side length. The square has a side length of 3 feet.
The surface area of the square =  square feet.
 square feet.
Step 4:
To calculate the total surface area we sum up all the individual surface area.
The total surface area =  square feet which is the third option.
 square feet which is the third option.
 
        
             
        
        
        
To add fractions, first convert them to have equal denominators.
3/4= 9/12 (multiply both sides by 3)
2/3= 8/12 (multiply both sides by 4)
From here, add the numerators while keeping the denominator.
9/12+ 8/12= 17/12
Final answer: 17/12 or 1 5/12
        
                    
             
        
        
        
Answer:
