A music fan claims that R&B songs and Rap songs differ in terms of their positivity. The individual collected two independent random samples from the population of all songs on Spotify. Fifteen R&B songs and another fifteen Rap songs were collected and their Valence was recorded. Remember, the variable Valence is measured on a 0 to 1 scale. Songs with high valence sound more positive (e.g. happy, cheerful, euphoric), while songs with low valence sound more negative (e.g. sad, depressed, angry). We will subtract (R&B – Rap) and use the 10% significance level. Assume the Central Limit Theorem conditions hold. The data set is called RBRapSample31. Please import the data set into Rguroo or find it in our group. Define the population parameter in context and symbols in one sentence. State the hypotheses you would use to test the claim that a difference exists in the mean Valence between R&B and Rap songs using correct notation.
