I am trying to solve this example in statistics, but my results are different from the ones in the solution and I do not understand why. The example say:
A study finds a test statistic $t$-value of $1.03$ for a t-test on a single population mean. The sample size is $11$, and the alternative hypothesis is $H_a:\mu \neq 5$. Using Table A-2 in the appendix, what range of values is sure to include the p-value for this value of $t$?
And the solution for this exercise is
$$0.20 < p\text{ -value} < 0.50$$
But the solution I get is
$$0.30 < p\text{ -value} < 0.40$$
Because if I go to the t-table, search for $ df=10 $ and search the values that contain $1.03$, it's between $0.879$ and $1.093$ which are $0.2$ and $0.15$. And after multiplying them by two because it's a two tailed test, I get my result.
My t-table:

$\begingroup$The result depends on wich table you read the result.
With my table
I get exacltly the result you are looking for
$0.2 < p <0.5$
Perhaps your table is more detailed
