Learn Polish: Najwyraźniej przepłaciliśmy za te bilety. - We evidently overpaid for these tickets.

The base verb is płacić (to pay). As you are learning in this lesson, adding the prefix prze- to a verb often indicates doing something in excess or crossing a reasonable limit. Therefore, przepłacić means to pay too much, or to overpay.

Why do we use the preposition za here, and what case does it trigger?

When talking about paying for a product or service in Polish, you use the preposition za followed by the accusative case. In this sentence, the phrase te bilety (these tickets) is in the accusative plural.

How is the word najwyraźniej formed, and what does it literally mean?

It is the superlative form of the adverb wyraźnie (clearly), which comes from the adjective wyraźny (clear or distinct). Literally, it means "most clearly," but it is commonly used as a set adverbial phrase meaning "evidently" or "apparently."

How would the verb change if a group of women were speaking?

The verb przepłaciliśmy has the -liśmy ending, which is the masculine personal form used when a group includes at least one male. If the group was entirely female, the non-masculine personal form would be used instead: przepłaciłyśmy.
