Answer:
The 95% confidence interval for the true proportion of bottlenose dolphin signature whistles that are type a whistles is (0.4687, 0.6123).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.
![\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}](https://tex.z-dn.net/?f=%5Cpi%20%5Cpm%20z%5Csqrt%7B%5Cfrac%7B%5Cpi%281-%5Cpi%29%7D%7Bn%7D%7D)
In which
z is the zscore that has a pvalue of
.
For this problem, we have that:
![n = 185, \pi = \frac{100}{185} = 0.5405](https://tex.z-dn.net/?f=n%20%3D%20185%2C%20%5Cpi%20%3D%20%5Cfrac%7B100%7D%7B185%7D%20%3D%200.5405)
95% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:
![\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.5405 - 1.96\sqrt{\frac{0.5405*0.4595}{185}} = 0.4687](https://tex.z-dn.net/?f=%5Cpi%20-%20z%5Csqrt%7B%5Cfrac%7B%5Cpi%281-%5Cpi%29%7D%7Bn%7D%7D%20%3D%200.5405%20-%201.96%5Csqrt%7B%5Cfrac%7B0.5405%2A0.4595%7D%7B185%7D%7D%20%3D%200.4687)
The upper limit of this interval is:
![\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.5405 + 1.96\sqrt{\frac{0.5405*0.4595}{185}} = 0.6123](https://tex.z-dn.net/?f=%5Cpi%20%2B%20z%5Csqrt%7B%5Cfrac%7B%5Cpi%281-%5Cpi%29%7D%7Bn%7D%7D%20%3D%200.5405%20%2B%201.96%5Csqrt%7B%5Cfrac%7B0.5405%2A0.4595%7D%7B185%7D%7D%20%3D%200.6123)
The 95% confidence interval for the true proportion of bottlenose dolphin signature whistles that are type a whistles is (0.4687, 0.6123).
1). Enrico Fermi directed construction of the the thing
that achieved the first sustained nuclear chain reaction,
under the stadium at the University of Chicago.
3). 'Fission' means splitting one big thing up into several
smaller things.
4). The atomic mass of an atom is close to the sum of all
the neutrons and protons in its nucleus.
5). 'Fusion' means several small things joining to form a
bigger thing.
6). Henri Becquerel is credited with discovering radioactivity.
7). The names of Madame Marie and Mssr. Pierre Curie were
appropriated after their deaths and used as the unit of radiation.
2). I have no idea what that symbol means, but 'neutron' is
the only choice left.
