Since the area between -11eb6b9e_0664_8e5c_8d9d_492d91266ba6_TB8220_11 and +11eb6b9e_0664_8e5d_8d9d_95083a7fab02_TB8220_00 is given as 0.9544, which corresponds to 2 standard deviations from the mean, and the value of 11eb6b9e_0664_8e5e_8d9d_bd20311ad5b1_TB8220_11 is given as 2.0, it is clear that the unknown z-score falls within this range. Therefore, the statement is true.
