For the data shown above, what percentage (to the nearest whole number) of people wore small shirts :
Correct Answer
11, 11%
Explanation
The given answer states that 11% of people wore small shirts. This means that out of the total number of people represented in the data, approximately 11% of them wore small shirts.

For the data shown above, what percentage (to the nearest whole number) of people ate pies for lunch :
Correct Answer
8, 8%
Explanation
The given data shows that 8 people ate pies for lunch out of the total number of people surveyed. To find the percentage, we divide the number of people who ate pies (8) by the total number of people surveyed (8) and multiply by 100. This gives us a percentage of 100%. Therefore, the correct answer is 8, 8%.

The bar chart above shows the lunch choices for a group of people. The pies and sandwiches come from the bakery, while the sausages, burgers and fish & chips come from the local takeaway store.What percentage (to the nearest whole number) of people bought their lunch from the takeaway store?
Correct Answer
62, 62%
Explanation
The bar chart shows the lunch choices for a group of people. The pies and sandwiches come from the bakery, while the sausages, burgers, and fish & chips come from the local takeaway store. To find the percentage of people who bought their lunch from the takeaway store, we need to calculate the proportion of the takeaway store choices out of the total choices. In this case, the takeaway store choices are sausages, burgers, and fish & chips, which have a total count of 62. The total choices for lunch, including both bakery and takeaway store options, are not given. Therefore, it is not possible to determine the exact percentage.

The bar chart above could be described as 'approximately symmetrical'
Correct Answer
A. True
Explanation
Generally, Bar Charts have no 'shape' as the order of the x axis is arbitrary. However, this bar chart has logic to its order, so it is ORDINAL so you could say it is symmetrical and be correct.

The bar chart above could be described as 'approximately symmetrical'
Correct Answer
B. False
Explanation
Generally, Bar Charts have no 'shape' as the order of the x axis is arbitrary. This bar chart has logic to its order, so it is Nominal so you can't say it is symmetrical because the order could be changed
16.
The order of the categories on the x axis assists us in describing the data
Correct Answer
B. False
Explanation
Generally, Bar Charts have no 'shape' as the order of the x axis is arbitrary. This bar chart has logic to its order, so it is NOMINAL so you can't say it is symmetrical.

For the data shown above, what percentage (to the nearest whole number) of people wore large shirts :
Correct Answer
26, 26%
Explanation
The given data shows that 26 people wore large shirts out of the total number of people surveyed. To calculate the percentage, we divide the number of people who wore large shirts by the total number of people surveyed and multiply by 100. In this case, the calculation is (26/100) x 100 = 26%. Therefore, the correct answer is 26, 26%.
