Fishing: Barbless Hooks In a combined study of northern pike, cutthroat trout, rainbow trout, and lake trout, it was found that 26 out of 855 fish died when caught and released using barbless hooks on flics or lures. All hooks were removed from the fish (Source: A National Symposium on Catch and Release Fishing. Humboldt State University Press).
(a) Let p represent the proportion of all pike and trout that the (i.e., p is the mortality rate) when caught and released using barbless hooks. Find a point estimate for p.
(b) Find a
(c) Cheek Requirements Is the normal approximation to the binomial justified in this problem? Explain.

Understanding Basic Statistics
- A marketing agency wants to determine whether different advertising platforms generate significantly different levels of customer engagement. The agency measures the average number of daily clicks on ads for three platforms: Social Media, Search Engines, and Email Campaigns. The agency collects data on daily clicks for each platform over a 10-day period and wants to test whether there is a statistically significant difference in the mean number of daily clicks among these platforms. Conduct ANOVA test. You can provide your answer by inserting a text box and the answer must include: also please provide a step by on getting the answers in excel Null hypothesis, Alternative hypothesis, Show answer (output table/summary table), and Conclusion based on the P value.arrow_forwardA company found that the daily sales revenue of its flagship product follows a normal distribution with a mean of $4500 and a standard deviation of $450.
