Final answer:
To find the area under the standard normal curve on the interval [-1.3,1.3], we can calculate the areas to the left of the corresponding Z-scores and find the difference.
Step-by-step explanation:
To find the area under the standard normal curve on the interval [-1.3,1.3], we need to calculate the area to the left of the Z-scores for -1.3 and 1.3 using a Z-table. First, find the Z-score for -1.3, which is approximately -0.9032. Use the Z-table to find the area to the left of -0.9032, which is 0.1831. Next, find the Z-score for 1.3, which is approximately 0.9032. Use the Z-table to find the area to the left of 0.9032, which is also 0.1831. Finally, subtract the area to the left of -1.3 from the area to the left of 1.3: 0.1831 - 0.1831 = 0.
