Given that:

$P(exactly\text{ }58\text{ }girls)=0.0223$
$P(\text{ }58\text{ }or\text{ }more\text{ }girls)=0.067$

You know that in order for the number of girls to be significantly high, the probability must be:

$P(x)\leq0.05$

In this case, you can determine that 58 girls in 100 births is a significantly high number, because:

$P(exactly\text{ }58\text{ }girls)=0.0223$

And:

Notice that the probability for exactly 58 girls is less than 0.05.

Hence, the answer is:

The relevant probability is

$P(exactly\text{ }58\text{ }girls)=0.0223$

so 58 girls in 100 births is a significantly high number because the relevant probability is less than 0.05.
