←A study considers if the mean score on a college entrance exam for students in 2005 is any different from the mean score of 499 for students who took the same exam in 1975. Let u represent themean score for all students who took the exam in 2005. For a random sample of 40,000 students who took the exam in 2005, x = 497 and s= 100. Use this information to complete parts a through cbelow.a. Find the test statistic.t = -4 (Round to two decimal places as needed.)b. Find the P-value for testing Ho: μ = 499 against H₂: μ#499.(Round to three decimal places as needed.)The P-value is...

claim : μ≠ 499n = 40000x¯ = 497s = 100here population standard deviation is unknown, so use t test
