Evaluate s(t)=∫t−[infinity]||r′(u)||du for the bernoulli spiral r(t)=⟨etcos(8t),etsin(8t)⟩. It is convenient to take −[infinity] as the lower limit since s(−[infinity])=0. Then use s to obtain an arc length parametrization of r(t).

In cooperation with high schools in the Athens area, he took random samples of 128 17-year-old girls and 122 17-year-old boys and asked them "Do you believe you have experienced romantic love?" 68 of the girls believed they had; 80 of the boys believed they had.a) What test would be appropriate here?Paired t-testTwo sample proportion test Chi-squared Test for Goodness of FitTwo sample t-testb) Given that the standard error equals 0.0621, what is the value of the test statistic? (3 decimal places)c) The p-value for the test was 0.0453. What could you say about a 95% confidence interval?The interval would go from 0.5313 to 0.6557.0 would not be inside the confidence interval. We would not be able to determine if 0 is or is not in the interval without first constructing the interval.0 would be inside the confidence interval.
