Before the furniture store began its ad campaign, it averaged 146 customers per day. The manager is investigating if the average is larger since the ad came out. The data for the 16 randomly selected days since the ad campaign began is shown below: 172, 147, 168, 163, 166, 139, 158, 151, 137, 140, 138, 137, 158, 133, 144, 144 Assuming that the distribution is normal, what can be concluded at the αα = 0.10 level of significance? D.)The p-value = (Please show your answer to 4 decimal places.) E.) The p-value is ? > ≤ αα F.) Based on this, we should Select an answer fail to reject accept reject the null hypothesis.
