Option 4 - 53

Step-by-step explanation:

Given : Lydia runs an experiment to determine if a coin is fair by counting the number of times a coin lands heads up. The table shows her data.

To find : According to the line of best fit, about how many times would the coin land heads up in 100 flips?

Solution :

We create the table of coin fairness table

Number of coin flips -  0    10    20    30    40    50    60    70    80    90

Number of heads up - 0    7       12    18      23    30    35    38    42    45

Now, using linear regression calculator,

We get the best line fit for the data

i.e,

Now, for heads up in 100 flips we substitute x=100

Graphically we plot the equation and see the point at x=100

The point is (100,52.935)

Or approximately the coin land heads up in 100 flips is 53.

Therefore, Option 4 is correct.
