Okay, so in my assignment I must use the following data: $(1)$ track name; $(2)$ artist; $(3)$ artist count; $(4)$ released year; $(5)$ released month; $(6)$ released day; $(7)$ in spotify playlist; $(8)$ in spotify charts; $(9)$ streams; $(10)$ in apple playlist; $(11)$ in apple charts; $(12)$ in deezer playlist; $(13)$ in deezer charts; $(14)$ in shazam charts; $(15)$ bpm; $(16)$ key; $(17)$ mode; $(18)$ danceability percent; $(19)$ valence percent; $(2)$ energy percent; $(21)$ acoustiness percent; $(22)$ instreuumentalness percent; $(23)$ liveness percent; $(24)$ speechiness percent. Okay, so then my task is to explore and analyze the spotify datset using graphical summaries created using R$.$ Create a min of $3$ properly labelled plots$/$graphs$/$figures that summarize some of the patterns in the data. It is recommended that you at least use $2$ different types of plots. For each plot, write a paragraph explaining the patterns and$/$or trends you see in the plot. $\{$NOTE: there is $156$ songs listed in the database$\}$ I$\text{'}$m just a bit confused on what to do$,$ regarding the R$-$code and evrurhing, I dont know, would someone just be able to help me$.$

We are interested in the proportion of songs that are in a major key. Answer the following questions using the Spotify dataset. All calculations should be done in R; please show your code and output.

a$)$ Test whether $50\%$ of songs are in a major key using a$=0\mathrm{.}1.$ State the hypotheses, calculate the Z$-$ statistic and p$-$value using R$,$ and state the relevant conclusion.

b$)$ Compute a $99\%$ confidence interval for the proportion of songs that are in a major key. You may use p $0\mathrm{.}5.$ Interpret the interval.

We are interested in average beats per minute of a song. Answer the following questions using the Spotify dataset. All calculations should be done in R; show your code and output.

a$)$ Test whether the average beats per minute of a song is equal to $124$ bpm using a$=0\mathrm{.}05.$State the hypotheses, calculate the test statistic and p$-$value using R$,$ and state the relevant conclusion.

b$)$ Compute a $90\%$ confidence interval for the average beats per minute of a song. Interpret the interval.
