Answer:

[tex]\text{1) }0.1141814[/tex]

[tex]\text{2) }0.6193473[/tex]

[tex]\text{3) }0.2003702[/tex]

Step-by-step explanation:

[tex]\text{1) }P(-0.3203\leq Z \leq-0.0287)=P(Z\leq -0.0287)-P(Z\leq-0.3203)\\\\=0.4885519-0.3743705\\\\=0.1141814[/tex]

[tex]\text{2) }P( -0.5156 \leq Z \leq1.4215)=P(Z\leq 1.4215)-P(Z\leq -0.5156 )\\\\=0.9224142-0.3030669\\\\=0.6193473[/tex]

[tex]\text{3) }P(0.1269\leq Z \leq0.6772)=P(Z\leq 0.6772)-P(Z\leq-0.1269)\\\\=0.7508604- 0.5504902\\\\=0.2003702[/tex]
