I need with step 4. I am so lost in solving it

The mean lactation (nursing) period of all earless seals is ?7 days. Grey seals are one of several types of earless seals. A sample of 40 female grey seals had the following lactation periods, in days: 23 3 25 4 33 242 246 27.1 24 6 23 2 245 295 20 9 27 1 26.3 30.2 227 24 2 25 8 29 2 27- 2246 21 4 20.1 21 2 229 228 24 5 25.8 21 3 27 6 89 28.6 24 3 21.8 23.1 272 24 8 20.9 33 21 5 284 At the 5% significance level, do the data provide sufficient evidence to conclude that mean lactation (nursing) period of grey seals is greater than 22 days? Assume that the population standard deviation is 3.5 days. (Note: The average and the standard deviation of the data are respectively 24.9 days and 3.35 days.) Procedure: One mean Z Hypothesis Test Assumptions: (select everything that applies) Sample size is greater than 30 Population standard deviation is known Simple random sample The number of positive and negative responses are both greater than 10 Normal population Population standard deviation is unknown Step 1. Hypotheses Set-Up where Vy d is the Ho = P - 22 population mean and the units are days Ha : - and the test is Right-Tailed 22 Step 2. The significance level a Step 3. Compute the value of the test statistic: [= - 5 240 w| Round the answer to 3 decimal places) Step 4. Testing Procedure: (Round the answers to = decimal places) CNA PVA Provide the critical value(s) for the Rejection Region: Compute the P-value of the test left OV is and right Cv is Pryvalue is
