Male penguins that weigh more than 4710 grams are considered "desirable" because the extra fat means they can babysit the couple's eggs without needing to wander off in search of food. In a random sample of 900 male penguins, how many would we expect to be considered "desirable"? This question requires a numeric input; no work or units are necessary. Make sure to include 4 decimal places.

The distribution of weights of male Adelie penguins on Torgersen Island is
assumed to be normal with a population mean weight of 4035 grams and a
population standard deviation of 375 grams.
Q7.1
The bottom 1 percent of the weight distribution of male penguins are identified as
chicks.
1. What is the most that a male penguin can weigh to be considered a chick?
2. Given that a male penguin is a chick, what is the probability that it weighs less
than 3000 grams?
Provide your answers to these two questions with either a file upload OR in the
following text box, clearly labeling each of the two parts.
Remember: for questions that involve calculations or derivations, you must show
the setup of the problem (your thought process in terms of the statistical
content). Your solutions must include the following, when appropriate:
Z-Score
• units
formulas.
