One or more of your responses is incorrect. At least one of your answers is incorrect. Reject the null hypothesis if the test statistic is greater than the critical value-then there is sufficient evidence to conclude that H₁ is true. Otherwise, do not reject Hō and conclude that there is not sufficient evidence to support the statement in H₁. OK X s in part (a). P-value = 0.001 (Round to three decimal places as needed.) d) Write a conclusion based on the results. Choose the correct answer below. Do not reject the null hypothesis and claim that there is not sufficient evidence to conclude that the population mean is greater than 22.

There is always a claim that after measles immunization, children develop hightemperature. A researcher at IHK was interested in finding out the validity of thisclaim. On a designated immunization day, he randomly selected 5 children (withnormal temperature before being immunization). He measured their temperatureagain 6 hours after being immunized against measles. The following were theirtemperatures in (0C): 37.7, 36.7, 39.3, 38.2 and 35.9.a) Is there evidence that the measles vaccine leads to increase in a child’s temperaturefrom the normal temperature of 36.7 (0C)?
