30. A researcher had originally planned to collect a sample of size 200, and conduct a hypothesis test with a 5% significance level. Now, she has decided instead to collect a sample of size 300, and conduct a hypothesis test with a 1% significance level. How will this change affect theA probabilities of type I and type 2 error?The probability of type 1 error will decrease, and the probability of type 2 error will increase.The probability of both type 1 and type 2 error will decrease.The probability of type 1 error will decrease, but it's impossible to determine whether the probability of type 2 error will increase or decrease.The probability of type 1 error will increase, and the probability of type 2 error will decrease.The probability of type 2 error will decrease, but it's impossible to determine whether the probability of type 1 error will increase or decrease.

30. A researcher had originally planned to collect a sample of size 200, and conduct a hypothesis test with a 5% significance level. Now, she has decided instead to collect a sample of size 300, and conduct a hypothesis test with a 1% significance level. How will this change affect the A probabilities of type I and type 2 error? O The probability of type 1 error will decrease, and the probability of type 2 error will increase. o The probability of both type 1 and type 2 error will decrease. O The probability of type 1 error will decrease, but it's impossible to determine whether the probability of type 2 error will increase or decrease. O The probability of type 1 error will increase, and the probability of type 2 error will decrease. o The probability of type 2 error will decrease, but it's impossible to determine whether the probability of type 1 error will increase or decrease.
