I get an error for the Berlin map: Error in get_googlemap(centre=location, zoom=zoom, maptype=maptype,: HTTP 400 Bad Request The Google Maps Platform server rejected your request. The provided API key is invalid. I would also like to calculate the daily NAO values (from the open data servers) in monthly averages. From 1950 to 2022, in 12 months per year, which means 72*12 calculations in the end. These NAO monthly averages should be integrated into the dataframe with the monthly precipitation averages anyway.

Question 1.1 During the holiday season, it has become a common trend among department store customers to purchase gift cards. In order to measure the extent of this practice, a store randomly selected 120 men and 120 women between December 26th and 29th and asked them if they had purchased at least one gift card. Out of the respondents, 36 men and 54 women answered positively. The store manager believes that the percentage of women who purchase gift cards is higher than the corresponding percentage of men. Do these data support the store manager's contention? To respond use both p value and the test statistic (use a level of significance alpha = 0.05). Question 1.2 Are there any differences in your response to Question 1.1 if the store manager believes that the percentage of women who purchase gift cards is at least 10% higher than the corresponding percentage of men? Please state all the variations in your response in Question 1.1. Question 1.3 Using the data of Question 1.1 compute a 90% confidence interval for the difference in percentages of men and women who purchase gift cards during the holiday season. Based on this interval, can we conclude that the percentage of women who purchase gift cards is higher than the corresponding percentage of men, as suggested by the store manager? Please provide your answer without conducting a hypothesis test.

Given the vector \textbf{F} = -y\hat{\textbf{i}} + x\hat{\textbf{j}} in Cartesian coordinates, write down the vector's representation in spherical coordinates. That is the vector should be written in terms of the coordinates r, $\theta$, $\phi$ and the spherical unit vectors $\hat{\textbf{r}}$, $\hat{\theta}$, $\hat{\phi}$. You may either submit this online or submit a paper copy in class. [3 points]

2 Explain what you did (a) Briefly explain how to do the teleportation protocol, how is it different from super- dense coding? (not in the scope of qiksit, just in general) (b) Does it matter which bell state you use in teleportation? (c) Going beyond, what would we need to teleport bigger states of multiple qubits?

eigenvalues and eigenvectors, if indeed the series converge. The eigenvectors are only determined up to a phase, $\Psi_n(\lambda) \to e^{ia(\lambda)}\Psi_n(\lambda)$, and we may adjust this phase so that $\langle \Psi_n^{(0)}|\Psi_n^{(k)}\rangle = 0$ for $k = 1, 2, \dots$ (4.101) We now substitute these power series expansions into the eigenvalue equation $\hat{H}(\lambda)\Psi_n(\lambda) = $
