Can you explain how to do on TI-84 .

Trials in an experiment with a polygraph include 98 results that include 23 cases of wrong results and 75 cases of correct results. Use a 0.05

significance level to test the claim that such polygraph results are correct less than 80%of the time. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method. Use the normal distribution as an approximation of the binomial distribution.

1. The test statistic is

2. The P-value is

3. What is the conclusion

PLEASE EXPLAIN HOW TO DO ON TI-84 You wish to test the following claim (HAHA) at a significance level of α=0.02α=0.02. Ho:μ=54.2Ho:μ=54.2 HA:μ≠54.2HA:μ≠54.2 You believe the population is normally distributed, but you do not know the standard deviation. You obtain the following sample of data: data 41.7 40.8 40.8 76.1 71.1 60.1 44 46 50.1 56.1 What is the critical value for this test? (Round to the thousandths) critical value = ±± Enter the data into L1 and make sure to...

Can you explain how to calculate with TI-84 calculator if possible? Thanks will rate! 1) This exercise uses the normal probability density function and requires the use of either technology or a table of values of the standard normal distribution. The cash operating expenses of the regional phone companies during the first half of 1994 were distributed about a mean of $29.77 per access line per month, with a standard deviation of $2.65. Company A's operating expenses were $28.00 per...

How do you do this on a ti-84 calculator? Assume adult females have pulse rates that are normally distributed with a mean of 74.0 beats per minute and a standard deviation of 12.5 beats per minute. If 16 adult females are randomly selected, find the probability that they have pulse rates with a mean between 78 beats per minute and 90 beats per minute.
