a claim is made that 23% of adults consume at least one energy drink per day. believing the true population parameter is larger than this claimed value, a researcher surveys a random sample of 300 adults and finds that 75 consume at least one energy drink per day. a hypothesis test, conducted a significance level of 0.05, yields a test statistic of 0.8, leading the researcher to conclude that the probability of observing a sample result at least as extreme as what was observed, under the assumption the null hypothesis is true, is approximately 0.21. the value of p is equal to _________.
enter your answer in the textbox below. to earn credit, your answer must be expressed to exactly two decimal places.

Explanation:

Step1: Recall the definition of p - value

The p - value is the probability of observing a sample result at least as extreme as what was observed, under the assumption the null hypothesis is true.

Step2: Use the given information

We are directly told in the problem statement that "the probability of observing a sample result at least as extreme as what was observed, under the assumption the null hypothesis is true, is approximately 0.21"
